[SR-Users] Kamailio 5.3.2 - Signal 11 on startup

[Daniel-Constantin Mierla]

Hello,

that seems to be an issue exposed in a rare situation, like a quick
retransmission of the same dmq command, which can result in processing
the same dmq command in parallel by two worker processes. That was what
I got to understand after analyzing the bug report...

Cheers,
Daniel
