Squid 5.0.4 crash

Moti Berger
Hi

I noticed Squid sporadically crashes with the following error (taken from cache.log):
2021/04/01 21:58:03| FATAL: check failed: !request->pinnedConnection()
    exception location: FwdState.cc(1055) connectStart
    current master transaction: master4104
2021/04/01 21:58:03| Removing PID file (/var/run/squid.pid)
    current master transaction: master4104


We run it in a container in a t3.small EC2 instance.
It crashes dozens of times a day, can't tell what triggers it (always with the same error, beside the master transaction number).
I can attach the logs and squid.conf, around 7MB compressed.
Please advise what's the preferred way of sharing them (or part of them).

Thanks,
Moti

Re: Squid 5.0.4 crash

Hi

I would like to share also that we haven't encountered this error before, also when using 5.0.4.
We see that this error is in correlation with an error from networkd-dispatcher:
ERROR:Unknown interface index 37 seen even after reload 

We looked a month back in our logs for this error from networkd-dispatcher and we found none.

The changes we made before seeing the error for the first time were:
  1. Add a new ICAP server to RESPMOD (we already had two on REQMOD and one on RESPMOD).
  2. Start using the ICAP header X-Next-Services
  3. Start using the adaptation_masterx_shared_names conf.
Maybe you can think of something related to above that might caused it?

Thanks,
Moti
