Hello,
I think guys from sems mailing list will be able to answer faster. Some
are also here, but the traffic size may hide such subject and they are
not able to spot it quickly. Also, getting it archived on the sems
mailing list will make easier to find for people with same problem in
the future.
Cheers,
Daniel

Hi,
I derived a SEMS module from ann_B2B for ringtones I got a segmentation
fault after a few calls.
It works like this:
Call comes in and a ringtone (e.g. sound files) is played. In parallel I
call callee with connectCallee(). When Callee replies positive ringtone
stops. When caller sends a Bye befor Callee replies I close the ringtone
file, call setStopped() and dlg.bye().
My test is like this:
I place a call and get the ringtone. SEMS tries to connect to callee in
parallel. Then I hang up (sending a Bye). SEMS stops ringtone and
session with caller.
I do the test number of times until a segmentation fault occurs. SEMS
logfile is like this, when test seems to be ok:

Segmentation fault
It seems to me that there happens something in process handling of SEMS.
I have no special process() function in my module
Any ideas?
