PFsense hanging since version 2.4.4


  • Rebel Alliance Netgate Administrator

    It's tricky to time it right, if you have an external logging server this is where it get's helpful.

    Basically you want to get a copy of the system log right after a reboot, sometimes there is info logged in /var/crash that can be helpful.

    If there is nothing logged, chances are high it's hardware related, and it's starting to fail out (RAM, HDD, etc).



  • I wish I could point you to something more specific, but I can tell you that I've been running PFsense for 10 years since v1.2.3 and every problem I've had in that time frame has been linked to hardware issues.

    I had similar symptoms a few weeks back where it would appear to crash every 3-7 days. In my situation, the symptoms started with no internet, next I found I couldn't ping PFsense, next while investigating the box I would find the PS fan whining loudly on full blast. My box is headless so I couldn't see the console, but a reboot seemed to set everything right for another 3-7 days.

    After each crash, there was a crash log waiting for me in the GUI, which I'm not familiar with parsing, so I started investigating my hardware before I posted my crash logs in the forums. Upon opening the case, I found my CPU and front intake fans caked with dust and a loose SATA cable on my HDD. So, after blowing out all the dust in the case, re-seating the SATA cable on my HDD, re-seating the RAM, and replacing the PS... the frequent crashing went away and PFsense has now been stable for the last 3+ weeks.

    Before my recent hardware issues, my box would stay up for 6-12 months at a time.... only going down due to forced reboots on firmware updates. Otherwise, there's no telling how long my uptimes would be.

    No software is perfect, but my money is on something in your hardware. I would do a deep dive into your hardware (e.g. blow out dust, re-seat connections, re-seat the RAM, try new RAM, etc, etc). After that, post the crash log here.

    When you say system log is that the system.log in /var/log? In that case it does not contain anything during the crash or before when it happens... /var/crash is empty so i guess it points to a hardware issue..

    I have taken the mini pc apart. No dust in it since its fan-less system. I removed the M2 drive and RAM and put them back again just in case.

    I also removed the Wifi chip in it since i do not use it anymore and one less problem cause to worry about :)

    Yeah.. I had a nightmare with another system here a few months ago.. Windows system. It did bluescreen now and then.. After about 1-2 months searching for the fault, checking drivers, viruses, replaced hd, reinstalled windows on another hd, replaced the RAM sticks, changed GFX card and finally i replaced the PSU and that solved the problem! .. I have never in my 25-30 year PC career have had a faulty PSU that created blue screens... i even measured the old PSU with a Fluke measuring tool and the voltages seemed fine and no fluctuation what i could find... But bluescreens happened sporadically .. 1-3 days apart...

    Anyway... thats off topic.. haha..

    I opened the mini-pc.. no dust (fan less) removed RAM and Disk and put back again... Removed WIFI-mini chip. I will let it run for a few days now and see... If it crashes again i will move the machine to a stable 12V power supply to rule out the PSU (thats the easiest thing for me to test right now) .. After that i have to decide if i should buy new RAM or HDD first... What do you think? :)

    How old is the system?



  • @chrismacmahon said in PFsense hanging since version 2.4.4:

    How old is the system?

    It's from 1st of April 2017 so not very old..

    It is ordered from Aliexpress.com though...........

  • Computer hanged again.. After 1day and 8 hours. I will update to 2.4.4 p2 and if it hangs again i will connect it to another PSU to test one thing each time.. Will let you know in here to help out others maybe :)


  • Rebel Alliance Netgate Administrator

    It sounds like it's hardware.

    I'm not in your shoes, but chasing hardware faults is difficult at best sometimes.

    When I had this happen 10 years ago, in my home, my wife insisted i fix it.... I ended up buying new hardware as that was the fastest path to resolution. Good luck!



  • It hung again. So now im running on another PSU. Also running a memtest now with Memtest86+... Will keep you updated... :) When it hung the console screen were just frozen and no special messages.

    If it freezes again next step is to run it from USB stick i guess...
    If it frezes then i will test older releases of pfsense.

    This is a hardware fault.

    If you have another device to swap out I would do so, or if you can run a VM to test I would.

    A VM to test what exactly? A VM of my current installation?

    The router hanged again an hour ago. Im now making a USB stick to try to run my config from it if possible... Live.


  • Rebel Alliance Netgate Administrator

    If you have the hardware to spin up a virtual machine, you can import your working config into the VM and run off of that.

    ok.. i dont have a ESXi machine at home.. but at work.. i will try to reinstall 2.4.4.. on the computer first.. or run 2.3 if that failes.



  • i tried to create a USB stick with 2.4.4 p1 but after installing i get into that crappy serial console bug.. i pressed ESC to type "set kern.vty=sc" but then booting into multi user mode i seem to get a crash.. text scrolls by too fast for me to read.. so after ESC i want to boot into single user mode to be able to see the boot errors.. but how do i boot from CLI (ESC) into single user mode.. i have tried to google for it but cannot find anything... i tried like boot single and such without success.. please help!

    I really wanted to try 2.4.4 before i go back and try 2.3 or something that might work better...


  • Rebel Alliance Netgate Administrator

    Not sure, I would re-burn the image, try again...if it happens again the hardware issue is the problem.

    We are a fan of Etcher.io



  • Found it... "boot -s" it is :) .. Will try it and review the logs.



  • Had to run fsck -y a few times due to unclean system because i did a power off because of the display issue in 2.4.4.. i did not realize the system would start up anyway..

    So now the system is up .. 2.4.4 p1 with basic settings.. Nothing changed except password.. will let it run like that to see what happens.. if it hangs again i will try to go back to an old version where i know it was working... to rule out software too...

    Is there anyone that has an older image available? 2.4 or 2.4.1 or 2.4.2? that i could have to test?



  • Another thing... i found this...

    Intel Atom systems containing HD Graphics chipsets similar to the Z3700 may experience console problems after the update. Affected systems will boot successfully, but fail to display console output after the boot menu. To fix the problem, add the following lines to /boot/loader.conf.local:
    
    i915kms_load="YES"
    drm.i915.enable_unsupported=1
    Systems with similar console problems not containing a graphics chip supported by the i915 driver may need to reinstall 2.4.4 to use a UEFI console.
    
    Alternately, try using the syscons console instead of VT in /boot/loader.conf.local:
    
    kern.vty=sc
    

    I have been using kern.vty=sc.. but i see i can enter the other stuff instead... Could this be a source of my problems i have had? I'm running Atom with Z36xx or Z37xx gfx chip..

  • Ok.. i entered:
    i915kms_load="YES"
    drm.i915.enable_unsupported=1

    Into /boot/loader.conf.local

    I now have much smaller text on the monitor connected to the system (VGA) when i boot the system than i have had before.. Maybe this could have been the issue why i had system freeze? .. I will run with the default config for 2 days... if no freeze i will load my config into the system and see if everything works as it should....



  • This looks promising.. I really hope this was the issue.. seems like it though... Uptime of 2 days and 6 hours now.. I will let it run until 3 days then i will apply my own config..

  • While you're applying, switch to p3.



  • @gertjan said in PFsense hanging since version 2.4.4:

    While you're applying, switch to p3.

    That one seems not to be available.. At least not in the stable brand. Is there some improvements for the problems im having?



  • Ok. I think i found the problem. The problem were infact not Hardware fault but it was software "fault" related to the 2.4.4 releases.

    When installing 2.4.4 the bootup changed to console display instead of VGA display. To fix that i found articles that i should add:
    kern.vty=sc
    To my /boot/loader.conf.local
    But that seemed to have caused the system freezes i have had.

    I now found another article that i should add the following to /boot/loader.conf.local
    i915kms_load="YES"
    drm.i915.enable_unsupported=1

    THAT solved my problems it seems like!

    I still have to apply my original config though to verify. I will do that now.. System has now been running fine for 4.5 days.

    You're right : it should be p2 - sorry.



  • @unb2b said in PFsense hanging since version 2.4.4:

    may i know how old your pc does it supported?

    If you read the thread you will find out.. it has already been mentioned. Computer is from 1st of April 2017 so not very old.



  • My backup with all configuration has now been applied.

    Lets give it a few more days too see if this is a complete solution or not :)



  • Ok. After applying my config system hung after 2 days again. So i suspect there is something wrong with my config since v 2.4.4... Or my 2 OpenVPN tunnels or something else causing the system to crash. Any advices how to go forward? I think i have established that this is not a hardware issue anymore?



  • And it hung again this morning. I reverted back to factory default settings now to get it stable again..



  • @taz79 Maybe you'd want to open the box and see if there are any swelled or popped capacitors. Just a thought.



  • I have replaced the pfsense router with a dovado router in the meantime. I will see if i could find some other hardware i could use instead :( ... As a last resort i will try to use an older version of PFsense on the router in a last hope there wont be a hardware issue :) .. But yesterday the router hung again with default config this time :(



  • Ok.. Setup with both 2.3.5 and 2.4.3 did lockup and hang with a flickering screen.. So as a few of you said in the beginning.. Hardware trouble.. I guess this PC will end up in the recycle pile :( Thanks for the help and input everyone!!! :)



  • Probably gonna try to buy a SG-1100 instead :)
