[OpenSIPS-Devel] Potential Memory Leak and a Memory Dump

[Ryan Bullock]

I believe I am hitting a memory leak in opensips. We receive 'out of
pkg' memory errors after a few days of runtime, a quick restart of the
service seems to clean up the problem. I manged to get a memory dump
from opensips during the last occurance.

Memory Dump Log:

(this is rather large, decompresses to around 700mb)

Can anyone provide some advice on how to proceed? I am not entirely
sure how to interpret the memory dump.

I apologize if this is not the correct list to post to, but it was the
one listed at http://www.opensips.org/Resources/DocsTsMem
