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.
