[Freeswitch-users] Getting to the bottom of a problem

Check dmesg - does it show that freeswitch crashed? You'll see a line about
segmentation fault, general protection error, or similar.

If so, do you have a coredump? If you're using the Debian packages (and
perhaps if otherwise) it'll likely be /var/lib/freeswitch/core

If so see 'Creating A Backtrace With gdb (Linux/Unix)' on
https://confluence.freeswitch.org/display/FREESWITCH/Reporting+Bugs and
file a Jira
