[Freeswitch-users] Freeswitch silent crash

[Steven Ayre]

I think the coredump request was for this crash:
freeswitch: pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion
`mutex->__data.__owner == 0' failed.
Which sounds independant of the silent crash.

Dmesg will always show either a segfault/general protection message. It's a
ring buffer so the oldest entries will disappear so you can also check
/var/log/messages.log. It'll always show a *crash* - it won't crash
silently if it is indeed a crash. It won't show a program exiting normally
though (eg a script calling exit) and for normally exiting programs you
won't get a coredump.
