How do I add debug symbols? I tried to compile with DBG_QM_MALLOC, but, the
system started with memory errors.

Hi

This happened to me alot of times, sometimes on systems without much load (
but with TLS )  .
Here is a log file (opensips 1.7.2):

I hope it helps.

Cheers,

Message:
Hello,

Your core doesn't seem to have debugging symbols, so it's a little bit hard
to trace the issue.
At first glance, it seems like a case of memory corruption.

If the issue appears even after updating to the latest 1.7 SVN, can you
please enable debugging symbols and provide us access to some core files so
I can have a look ?

Regards,
Vlad

version is 1.7.x. I have updated the software with the latest SVN. The
problem is intermittent and occurred 5 times from July 27 to August 20.
Waiting to see if it will happen again after update. I have all the core
files (1GB each).
