Hi Daniel.
See https://opensips.org/Documentation/TroubleShooting-OutOfMem on how
to do proper mem dumping. List again the output please.

Hi,
I'm facing a shared memory leak on OpenSIPS 3.4.16. SHM is set to 2
GB, and its usage keeps increasing over time until the process
crashes. This usually happens after 1–2 days of uptime.
I do have a custom billing module, originally developed for OpenSIPS
1.11.x and later ported to 3.4.x. While the module is a suspect, I'm
also trying to rule out other possible causes in the core or standard
modules.
I generated the following |mem_shm_dump| after 24 hours of traffic, at
a moment with no active calls:

Any hints or suggestions on how to further investigate this would be
greatly appreciated.
