[OpenSIPS-Devel] Clusterer module and memory leak!

[Liviu Chircu]

Hi Samy,

If you happen to have the code compiled with the "DBG_MALLOC" flag and 
catch your OpenSIPS in this state again:

* opensipsctl fifo log_level 14 <pid which went oom>
* kill -SIGUSR1 <pid which went oom>
* opensipsctl fifo log_level 3 <pid which went oom> (restore it to 
whatever it had before)

This should make that process dump its memory map in the logs, so we can 
tell where the leak is at.

Regards,
