This started happening after we enabled server certificate verification. Datadog is showing a steady memory usage increase whereas previously it was flatline. The changes we added were:

[server:default]
method = TLSv1.2
verify_certificate = yes
require_certificate = yes
private_key = /etc/kamailio/kamailio.key
certificate = /etc/kamailio/kamailio.crt
ca_list = /etc/kamailio/trusted_roots.crt

Previously we had client verification enabled but not server:

[client:default]
method = TLSv1.2
verify_certificate = yes
require_certificate = yes
ca_list = /etc/kamailio/trusted_roots.crt
private_key = /etc/kamailio/kamailio.key
certificate = /etc/kamailio/kamailio.crt

I'm sorry you are correct, the version we are running is 5.2.5. I've just run ulimit -c unlimited to hopefully get a core dump next time since I don't see one in /var/lib/systemd/coredump/. Not sure if there is anything I need to do to get a coredump.
The log just shows:

If you use the repo listed at http://deb.kamailio.org/ , then it should be 5.2.5, and there is also option to install 5.2 branch debs built nightly.

Cheers,
Daniel

I'm using ubuntu packages, I believe 5.2.3 is latest?

Hello,

that log message is irrelevant for actual crash. Did you get core files? Or other log messages before the one you pasted?

You should upgrade first to latest 5.2.x, either 5.2.5 or latest branch 5.2.

Cheers,
Daniel

I'm seeing this in the log and kamailio is crashing every hour or so:
CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 33/var/log/kamailio/kamailio.log

Any ideas? Should I emergency upgrade to 5.3.1?
