[Freeswitch-users] mem leak and core dump

[Freeswitch Freeswitch]

Hello,

Now I have updated to the latest trunk as of Nov 21 and moved to a fedora 7
system.

Still chasing random crashes of FS.  First time this happened last night
there were around 1000 sessions up.
Crit error was logged referring to a signal caught on an unmapped thread.  I
wasn't able to catch the specific signal in the console before it scrolled
off.  This morning I had another crash.  This time around 200 sessions
running.  There was no logging reported during the second crash.

Calling scenario is about as simple as it gets.

gw1 -> freeswitch -> gw2 all sip
codecs, 729 and 711
transcoding off

I have been playing with the various rtp knobs in the sofia conf.  Sometimes
running with rewriting rtp timerstamps, sometimes not.  Also tried with soft
timer and off. ( can someone point me to an explanation of what the soft
timer does? ).

Also notable that I compiled the code with debug symbols.

No core has been generated during crashes.  Is there some way to enable core
dumps?

Overall I am very impressed with FS - would love to get the cause of these
crashes nailed so I can press forward.

Any help is very much appreciated.

Best regards,

Tom
