[OpenSIPS-Devel] Possible memory leak OpenSIPS 1.7.2

[Steven Lam, KeenSystems B.V.]

Hi,

The -M parameter did not work in my setup, so I recompiled OpenSIPS after changing PKG_MEM_POOL_SIZE to 1024*1024*4.
Even now OpenSIPS stops after handeling many calls.

I now made a test setup with the same config, only with "children=1". Than I fired calls at it with sipp.
Here the same happens.

With htop i can see the memory usage for the one child go up, the memory usage never goes down, not even after being inactive more than one hour.

After a while OpenSIPS starts complaining "ERROR:core:pv_sprintf: pv_sprintf: Memory exhausted! "
I than did a "kill -SIGUSR1 OPENSIPS_PID", the log can be found here: http://keenserver.nl/files/dump2.log.tar.gz

I really hope someone can help, as I really do not know what to do next.

Thanks, Steven
