Hi!
We recently upgraded our Kamailio 4.1 to 4.2.1. With the newer version Kamailio
crashes after just running a few minutes. After some debugging it looks as
though the problem is in exec_msg (which is used in our config). After
disabling this 4.2.1 seem to run just fine.
Core file exists, here's the output:
