Kamailio v5.2.2 rev. 9bc44f randomly crashes once a week. The problem seems to be related to TM and ASYNC modules as seen in back-trace of dump core below.
None. We have dump core file available for analysis.
Randomly, roughly once every 5 to 7 days.
Program terminated with signal 11, Segmentation fault.
