Re: [SR-Users] jsonrpc_exec crashes kamailio

Hello, I understand. I'll get you the logs. Yes, I did run the ulimit command. Do I need to do anything else? Or get the logs from somewhere else? # ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 7928 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 7928 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited From: Daniel-Constantin Mierla [mailto:miconda@gmail.com] Sent: Wednesday, April 1, 2015 11:26 AM To: Grant Bagdasarian; Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] jsonrpc_exec crashes kamailio Hello, I need the logs printed by kamailio before the crash, to see what was processing at that time. After crash is no information in the logs printed by itself why it crashed . The traces printed in syslog by the kernel are not easy to use for troubleshooting and I see the core was not generated to use gdb for a proper backtrace. Have you run 'ulimit -c unlimited'?

I've only included the trace(see attachment) from the point kamailio crashed, since it only happens when a certain condition inside the script is met. (if statement) But when the condition is met, it crashes every time. If you need more information, please let me know.

Or is it happening from time to time? If you can reproduce, set debug=3 and send all the logs to me. Also, it would be good to set 'ulimit -c unlimited' before starting kamailio to get a coredump which would be easier to troubleshoot.
