Hi Bogdan
You were right, found out the problem was a customization we did in a
module.
Didn't know that get_dlg_by_ids function adds a ref internally so the
dialog is never released. The problem is that this customization is
not called on every call, so leak didn't happen very often. Now we are
calling dlg_unref properly.

Thanks for helping out!

Hi Daniel,
The dump shows you have ~29K dialogs in memory....maybe your
billing module is messing up with the dialogs?

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.
