SG-4860 crashing daily
-
@stephenw10 This is currently the production firewall for this location. I purchased a XG-1537 last year and a stack of new switches to install but haven't scheduled a time to replace it all.
I'll try to reload the 4860 after everything stabilizes.
Last nights crash dump.

Mmm, another similar crash but different panic. Again it doesn't point to any specific thing and looks increasingly like a hardware issue unfortunately.

@stephenw10 The device hadn't crashed in a few days, but this morning it has a PHP crash log as well.
[12-Aug-2022 00:42:00 UTC] PHP Warning: Static function mbereg_search() cannot be abstract in Unknown on line 0 -
Hmm, that looks different, more like it just ran out of memory.
That also ties in with this:
<6>pid 71216 (unbound), jid 0, uid 59: exited on signal 11If you check the monitoring graphs in Status > Monitoring do you see memory usage increasing with time?
-
@stephenw10 I checked the memory graph for a 2 day period with 5 min resolution and didn't see the free memory decrease except during the crashes.
I'll keep a watch for anything new.
-
Mmm, I agree, it doesn't look like it's exhausting the memory directly.
-
@stephenw10 I believe I have narrowed the issue down to the tailscale package. I noticed when I came back from vacation that the firewall had been up over 8 days w/o a crash.
Checking the logs showed that either PHP or PHP-CGI was exiting on signal 11 with a core dump, and the services section showed that tailscale wasn't running either.
On a hunch I started the tailscale service yesterday morning to see if a crash would happen. Sure enough, last night it crashed again.
Attached is the latest dump. textdump.tar.0
-
So you had disabled tailscale while you were away? Or it had stopped by itself and then crashed after you restarted it?

@stephenw10 tailscale had crashed apparently, but the connections it made we're still running so I didn't notice the service itself was down.
I restarted the service yesterday morning to see if it was the cause of the crashes, then this morning when I logged in, I saw the crash report.

Mmm, not familiar to me. Let me see if any one else has seen it....
