Hello,

5.3.x is very old, no longer maintained. It is recommended to upgrade to a maintained version (5.6.x or 5.7.x), or at least the last version in the 5.3.x series if you can't do a major update quickly.

I recall some changes to the tm module over the time, not sure if they were during 5.3.x release, earlier or afterwards, but I don't think someone will spend time to dig in for an unmaintained version, it might be something that was already fixed.

Cheers,
Daniel

Hello!

 

We had several crashs of Kamailio (5.3.4) in the last weeks. Each time, the last logs are:

/usr/local/sbin/kamailio[20942]: CRITICAL: <core> [core/forward.c:347]: get_send_socket2(): unsupported proto 0 (*)

/usr/local/sbin/kamailio[20966]: CRITICAL: <core> [core/forward.c:347]: get_send_socket2(): unsupported proto 111 (unknown)

 

When we look to the coredump, here below the first traces:

Is there anything relevant in this to know what's wrong?
