Hello,
We suddenly had an issue on one Kamailio instance: we were not able to
restart. Kamailio started to boot and fork and suddenly crashed.
The last logs reported a failure regarding the ability to connect to one
MySQL instance.
I finally succeed to restart after increasing: fork_delay=5000 to
fork_delay=9000.
How this could happen suddenly? We already restarted Kamailio on this
server.
Regards,
Igor.

Hello Daniel,
Both Kamailio and MySQL are running under RHEL. But SELinux is deactivated.

Hello,
it can be some other limits set in the system, I encountered also with
centos/redhat and couldn't figure out myself (well, not a sysadmin
here). It is the reason I added fork_delay and modinit_delay. You have
to dig in the settings of the system and try to tune them.
Happening can be somehow random, a matter of how busy the system is at
that moment.
Cheers,
Daniel

Hello Daniel,
Thank you. Do you know some OS counters (in /proc I guess?) I can look to in
order to diagnose deeper?
Anyway, I'm already sure that the CAPS was higher than during another period
of time.
Regards,
Igor.

this is not about caps, but limits that prevent creating new tcp (mysql)
connections. Might be even mysql server limits (how many new connections
per second it accepts). I was not able to identify the limits, that's
why I added those delay parameters.
Cheers,
Daniel
