Hello, I've got a 13.13.1 system using PJSIP stack on debian Jessie. It runs from 50 to 100 simultaneous calls (so 100 to 200 PJSIP channels) all day long. >From time to time, roughly meaning once a month, it segfaults with lines (from dmesg -T output) like this: asterisk[1160]: segfault at 7efffffe ip 00000000005881d6 sp 00007fec95c33910 error 4 in asterisk[400000+2a2000]
Debug level was unfortunately not set in asterisk.conf but verbose level was set to 5. Asterisk runs with: /usr/sbin/asterisk -U asterisk -G asterisk -g Asterisk is compiled with DONT_OPTIMIZE and BETTER_BACKTRACES options. "core show settings" outputs: * Directories ------------- Configuration file: Configuration directory: /etc/asterisk Module directory: /usr/lib/asterisk/modules Spool directory: /var/spool/asterisk Log directory: /var/log/asterisk Run/Sockets directory: /var/run/asterisk PID file: /var/run/asterisk/asterisk.pid VarLib directory: /var/lib/asterisk Data directory: /var/lib/asterisk ASTDB: /var/lib/asterisk/astdb IAX2 Keys directory: /var/lib/asterisk/keys 1. Am I correct to expect a coredump file to be produced anytime asterisk segfaults ? 2. Does Asterisk prints any WARNING or ERROR message whenever it detects, at startup preferably, that it has not required permissions to write a coredump file ? 3. Among above directories, which one is choosen to save coredump files ? Is it something that can/should be configured in /etc/asterisk (I've seen related options in some debian /etc/default/asterisk files but I would be curious to know if such things exist 4. Is there anything useful I can do with a line such as : asterisk[1160]: segfault at 7efffffe ip 00000000005881d6 sp 00007fec95c33910 error 4 in asterisk[400000+2a2000] ? Any pointer ? 5. Suggestions ? Best regards
