Issue with SG-3100 and 22.01? [Solved]

[stephenw10]

Yeah the default config assigned mvneta0 as OPT so that might be expected to show as no carrier.

I did not install the SG-3100 from recovery image yet, just being curious if anything is logged at console.
I expect the next crash at May 1st or 2nd.
Up to now the SG crashes every 23/24 days.
A PC is connected to serial interface.

But anyhow, I have two more questions: as screenshot shows there is something creeping which decreases memory, any idea how to pinpoint this?

Second question: I noticed that when using this view I need to login again to pfSense after x hours (not sure about the exact value).
When in dashboard view I keep logged in for days!?
Seems that the duration for session depends to the view, is that correct?

Check what processes are using RAM in Diag > System Activity or run top -aSH at the CLI.

The dashboard has a number of active items on it that update periodically keeping the session open. On static pages the session times out after a while.

other commands you can use to show top memory-consuming procs:

show top 10 memory consumers

# ps -Am -opid,pmem,pcpu,rss,vsz,args | sort -k4 -rn | awk 'NR == 1 { print "  PID %MEM  %CPU   RSS    VSZ COMMAND" } NR > 1 && NR < 12 { print $0 }'

If you want a continuously updating display

# while :; do clear; ps -Am -opid,pmem,pcpu,rss,vsz,args | sort -k4 -rn | awk 'NR == 1 { print "  PID %MEM  %CPU   RSS
  VSZ COMMAND" } NR > 1 && NR < 12 { print $0 }'; sleep 1; done

or use top

# top -o res

This morning it happens again...
From one minute to the other, I was just noticing that accessing a web site was not possible any longer (404 - Not found).
Ping works to all addresses (i.e. 1.1.1.1, 8.8.8.8 or any other IP).
But ping to a name will not work, so DNS service was not doing.
After a few minutes WebGUI from SG-3100 was unreachable too.

After last issue I connected an old laptop at SG-3100 with serial connection, so I looked up for any console output and ... the laptop was in a deadlock as well!???
Very strange... need to reboot laptop and after looking up in Putty log I rebootet the SG-3100 by power cycling. There was nothing seen in log, nothing means really nothing since last reboot! Not a single character.
An existing VPN connection into company network was still working (until reboot of SG).
No idea what this is. Will use the replacement hardware during the next weekend.

Hmm, nothing appeared at the console at all?
At the very least you should have see webgui logins shown there. If nothing at all was shown it sounds like it was not logging.

Your description of the issue really 'feels' like a failing drive. That's exactly how it presents. Except that eMMC failures generally don't recover at power cycle.

If you have an m.2 sata SSD you could try that instead.

Hi,

no M2.SSD yet, but I will get one in the next days.
And no, me too was surprised, I looked in the last weeks from time to time at serial console, nothing was shown there. Sometimes I just pressed the ENTER key to see, if I am still connected to console, it was, but nothing was recorded since startup.

Regards

[stephenw10]

Hmm, well try just logging into the webgui to check. That should be shown, for example:

*** Welcome to Netgate pfSense Plus 22.05-BETA (arm) on 3100 ***

 7) Ping host                         16) Restart PHP-FPM
 8) Shell

Enter an option:

I have the same problem on my SG-3100 running 22.01. Roughly every 4-5 weeks the device freezes. I can ping the device/gateway address but not traffic goes through the WAN interface. DNS resolver/web GUI etc. does not work or is non-reachable.

I have a RasberryPi connected to it via USB-serial console and recording all the output using GNU screen to a text file. Nothing is recorded when this happens. Nothing particular is shown in boot log either. My knowledge of all the log files is however limited, so I might be missing something.

I ran S.M.A.R.T. tests on my M.2 SATA drive and no errors are shown. I see the similar memory graph as previous poster.

Any ideas or suggestion what to check next would be greatly appreciated.

Should I perform a re-install and restore config from backup maybe?
Register support ticker to Netgate?

[stephenw10]

Does the console still respond when this happens? Can pfSense connect out on any interface?

Do you see free ram drop to <10%?

This post is deleted!

[stephenw10]

Hmm, and you manually power-cycled it at that point?

[FSC830]

After it happens again this morning I finally replaced the device with the 2nd SG-3100 (which I didnt in the last weeks).
We will see, if it happens with this device too.
In the meantime I will start rebuild the replaced device from scratch.

Regards

Edit: Help needed: After exchange of the SG-3100 I am flooded with mails :"can't create socket: No buffer space available", I cant find any reason for that.
Exchanged the devices again, but also the other device (which stops working this morning) too send thousands(!) of this mails???
Whats happened now?
There are some threads with "No buffer space available", but they are all relating to ping, traceroute or any other networking command.
But I did not find any post with "cant create socket", any ideas?

Edit 2: no idea what has happened, but mails now stopped!??? Currently the device which stopped this morning is on duty again. Checked routes, NICs, updated some packages, and mails stopped. Whats a mystery!?

[pwyde]

@stephenw10 Correct. Can't do much else with no response from the device or WAN connection.

May be I was mistaken and there was a delay in mail receiving so that mails from device#1 arrived at mail client after device#2 was at work again. So I misinterpreted the mails as from device#2.

Anyhow: any idea what is causing this error?

That looks like what you see if the WAN is changed and it's still trying to monitor the old gateway.

[FSC830]

Yes, was my first thought that an interface is not working properly, but how can that be? The device was powered on, so in my understanding there cant be an old gateway?
Will boot up the appliance in an isolated network later and check the settings.
In dashboard the WAN interface was reported as good (no packet loss to monitoring gateway).

This morning device updated to 22.05.
We will see, if this "frozen" status will appear again in the next weeks...
Hopefully not.

Regards

[pwyde]

Also updated my SG-3100 to 22.05 today. Will find out if issue is resolved in about 3-4 weeks.

[FSC830]

@pwyde You've got a m.2 sata disk, mine is still runnig at eMMC.
Have the m.2 here, but did not found the time to install them.
But if yours with m.2 and mine with eMMC shows the same freezes, my guess is thats not to an unresponsive disk as suspected. We will see, usually within 3, max. 4 weeks the issue occurred since 22.01.
