[OpenSIPS-Users] OpenSIPS core dumps

[Bogdan-Andrei Iancu]

This last crash had the same bt as the one from previous email ? the 
prev fix I made reports this:
          ERROR:db_flatstore:flat_db_insert: uninitialized connection
and does not crash, so this time the crash may be in a different place.

Now, it seams after all that the root of your problem is the mem 
exhaustion. To see what  causes this  (if a mem leak or simply not 
enough mem), there is a doc - 
http://www.opensips.org/Resources/DocsTsMem (it is for shm, but the same 
for pkg).

Maybe, first you should simply try to increase the pkg mem ( in config.h 
you have PKG_MEM_POOL_SIZE that you can increase) - you NEED to 
recompile and reinstall after that.

If more pkg mem does not solve the problem, I can help you with using 
the memory debugger to see what is going on there.

Regards,
Bogdan
