New 502 Bad Gateway

jimp

DSNBL Default settings
I have 2 DSNBL Feeds, mostly for ads, and Malware

Approximately how many clients do you have on your local network that hit DNSBL? Any idea how busy it usually is?

The only Error messages we get are 502 Bad Gateway, but we can not access SSH without closing out process with CTRL-Z, and commands such as find, ect do not work. they just hang.

Most likely you just need to start a proper shell, try running /bin/tcsh

I have one site that has currently has

LAN 192.168.1.175 192.168.1.199 = 5 users
LAN 192.168.1.5 192.168.1.174 = 19 users

This site will lock up in less than 12 hours.

Another site

LAN 192.168.1.41 192.168.1.50 = 3 users
LAN 192.168.1.5 192.168.1.40 = 4 users

It will take up to 24 hours.

and another

Interface Pool Start Pool End # of leases in use
LAN 192.168.16.50 192.168.16.75 = 5 users

This one will take up to 24 to 48 hours. However since the last update 2.4.0.r.20171009.1758 it has been happening more frequent around every 12 hours itself.

I currently have the pfBlockerNG uninstalled on the top 2 because they are used for apartments, and didn't want to bug the tenants when it locks up the CP becomes unresponsive. However for testing purpose I do re-install, and let it run with any changes for testing. I can usually get a crash within 6 to 12 hours. or less sometimes.

Just a note the amount of users, has not changed from before to after this issue started. Load has remained the same.

Thank you, I will test the /bin/tcsh and see if that gives me a good shell again. I will test that now on the top 2, will have a result back after it crashes.

Thank you, any logs you would like to see, please let me know I will post as much as I can.

The devs can perhaps assist with tracing, meanwhile I'm simply once again annoyed by the course taken here. We've had this some ~3 years ago when the repos have been taken offline altogether, accompanied by some giant noise about trademark violations. It's getting old. Waste of time. Annoying. Disrespectful to people who've been contributing to pfSense, even after that CLA/copyright assignment/re-licensing nonsense etc. People wanting to build this thing for development purposes get absolutely zero assistance whatsoever and are being [url=https://forum.pfsense.org/index.php?topic=109089.0]deliberately sabotaged by the so-called build scripts.

Open-source touted all over the website, and all you get is this. Getting on a tipping point again here.

I never knew about that, I do not have any bad intentions for this. Sorry if I came off that way, I was not aware.

If it is related to memory or a connection or network queue, then in particular the output of these could be helpful:

/usr/bin/netstat -Ln
/usr/bin/netstat -xn
/usr/sbin/swapinfo -h
/usr/bin/top | /usr/bin/head -n7
/bin/ps uxawwd
/usr/bin/sockstat

Attach the output in a text file as it will be too large to put inline on a forum post.

I got home and my pfSense GUI and Serial Console was unresponsive. As stated earlier from a client point of view everything worked, wired and wireless connections in and outbound.

My setup is is almost the same as BreeOge's, with even less users. Only me with a lot of gadgets. When I left for work at 6am I had just restarted and everything worked. When I got home at 4pm it was in the reported condition.

2.4.0-RC (amd64)
built on Mon Oct 09 17:58:12 CDT 2017
FreeBSD 11.1-RELEASE-p1

What else can I provide?

Edit…. I also have openVPN with one user.

I have one box using the ZFS file structure, the other is using UFS, both using pfBlockerNG. The ZFS is rock solid, and the UFS one gets the Bad Gateway after some time. Wondering if that is a possible reason why two similar boxes with similar settings exhibit different behavior using the same snapshot and same packages.

Both running 20171009 Snapshots for 2.4.0

Just a thought

I don't know but I had planned to do a fresh install of my UFS pfSense to ZFS this weekend and restore the same config.

Very interesting mine are UFS as well..

I have a time frame on my pfSense. I had to reboot when I got home at 4pm. It's now 7:50pm and I am getting the 502 Bad Gateway error. I'm going to reboot and scrub the system log between those times and if someone want's to look at it fine. Regardless I'm going ahead with my plans to reinstall this weekend.

It locked, here is the logs from the info you wanted.. This is from my heavier load box. My low load box also crashed, I will make a new post for it.

Lots of port 1344, do you have squid+clamav active as well? Can you try shutting that off?

Also that netstat -x output is too big to put inline, you should attach that in a .txt file

I disabled squid+Clamav, when it crashes ill get ya the logs again for that as well.

Hi

This morning I could not connect to the GUI nor was the serial console working. I rebooted then downloaded the system.log
It was nothing but what you see below. I only posted the last few lines before I restarted the firewall. I hope this helps.

After scrolling through all 6,000 lines of the system.log file I see several of these lines they appear to be at 1 minute intervals

For that, check the current value of kern.ipc.soacceptqueue (run "sysctl kern.ipc.soacceptqueue"). It's probably at the default of 128. Set that to 1024 or higher (e.g. 4096), make a tunable for that under System > Advanced, Tunables tab.

Indeed it was set to 128. I added the tunable and set it to 4096 and applied. I'm doing this via openVPN connection. Do I need to reboot it?

No need to reboot, that is one that can be changed at run-time.

john_galt

Okay. Will keep an eye on it and thanks.

Now the SG-2440 boxes stopped working as well :( it lasted 6 days before I got 502 error. Now all of them are back running 2.3.4p1 and XMLRPC Sync is working as well. I will wait for the final release before I give 2.4 a new try.

Same thing here this morning. I had to force a reboot. I also increased sysctl kern.ipc.soacceptqueue to 4096 as suggested. While I was at it, I updated to latest build and it now says 2.4 RELEASE.
