Varnish stops working after few days
-
marcelloc, thank you for quick reply. Looking at the output (see below) varnish is the only service on 80 and it is running. No alerts that I can see.
There are 4 domains and 3 internal HTTP servers. No matter which domain I try to access from the outside, it always takes me to the first server that is configured under backends. Even after I removed the first backed, it still takes me to it no matter which domain I'm trying to access!
Any thoughts?

Something is really screwed up. I disabled varnish in gui and I'm still able to access the server behind pfs! Mind you, I still have original issue with being presented with the first backend regardless of the domain being access.
-
Check if there is a remain nat that forward requests to this first server.
With varnish stopped, you can't be able to reach backends.
Also check on system -> advanced if webgui redirect rule is disabled.
-
No NAT and webgui is disabled.
As I stated in the first post. Everything is working properly after the reboot. This system was running for almost two weeks w/o issues.
Not sure if it matters, but varnish was installed first then two weeks after squid & squidguard was installed. Could the order of installation make difference?

Probably not.
There is something really weird on this setup. With varnish stopped, you can get access to port 80 so how could it forward to internal host???? -
Had the same behavior on previous box, so I rebuild the whole solution on the new box. The issue showed up on the new build. Two different boxes with this bug.
Just rebooted pfs. Everything is working. The question is for how long. I have a feeling that it has to do with squid/squidguard. I guest next time it happens, I'll remove squid/squidguard and see if it'll make a difference.
-
It happen again! 10 days after the reboot varnish is malfunctioning.
-
Dear all,
I encounter the same problems…after a couple of days Varnish is stopped and won't come online until a reboot of pfSense. Then again a couple days later the system doesn't respond to my external requests. How come?
Thanks,

Is there any log or alert or message during manual service restart to help on identifying this problem?
I`m using it on amd64 for a long time without crashes.

Yes, after a couple of tests the following error emerge:
"php: : The command '/usr/local/etc/rc.d/varnish.sh' returned exit code '2', the output was 'kern.ipc.nmbclusters: 65536 sysctl: kern.ipc.nmbclusters: Invalid argument kern.ipc.somaxconn: 16384 -> 16384 kern.maxfiles: 131072 -> 131072 kern.maxfilesperproc: 104856 -> 104856 kern.threads.max_threads_per_proc: 4096 -> 4096 NB: Storage size limited to 2GB on 32 bit architecture, NB: otherwise we could run out of address space.

Thanks a lot,

canefield,
something is messing up config:

marcelloc, is there any particular command that I could run that would help with finding the root cause?
TIA,
Dave -
xudus,
try to run the startup command on console/ssh
/usr/local/etc/rc.d/varnish.sh restart
-
This is what I'm getting:

This is what I'm getting:
There is no varnish fatal errors on this log, so it should be runinng.
-
Sorry, it is running as I just restarted pfs. I'll post the output when it'll malfunction next time.
-
marcelloc, it did it again.
The output from /usr/local/etc/rc.d/varnish.sh restart is same as before (no errors). Is there any other place that I could poke to see what is braking varnish?
-
xudus,
check with netstat -an if varnish port are still up
check with ps ax | grep -i varnish if varnish is still running.You can also create a cron job to restart varnish after two days for example to prevent this random error.
att,

Marcello,
Varnish is running and port 80 listening (*.80). Restarting varnish does not help. Restarting pfs does.
-
I disabled squidGuard (1.4_2 pkg v.1.9.1) and everything is working so far for the last 14 days. I'll give it another week or two before re-enabling squidGuard again.
