[SR-Users] Segmentation fault in sip-capture

[Owen Lynch]

Hi,

I am running Kamailio 3.3 as a Homer capture agent, the sip-capture module
receives HEP packets from a sip-trace module in a remote kamailio instance.
Periodically the capture agent dies. The log and core dump suggest the
initial problem is an invalid HEP msg received, but kamailio crashes when
trying to send an error reply. Can anyone shed any light on this?

Thanks,
Owen Lynch
