[kamailio/kamailio] Setting notifier_processes to 1 or more seems to cause memory leak (#2733)

Hello,
We use Kamailio with KAZOO. We have set notifier_processes as follows:
modparam("presence", "notifier_processes", 1)
A value of 1 or greater seems to be required to avoid race conditions when multiple
notify's need to be sent.
We've noticed noticed what seems to be a memory leak in Kamailio process. After
several days, Kamailio will crash after consuming all system memory.
I have not found any other reports of this happening to others.
Does this seem familiar to anyone?

Thanks for the report.
Please specify the version of Kamailio that you are using ("kamailio -v")
Are you using the "official" kamailio version of some version with kazoo
specific patches? If the latter, then you should report this issue to the kazoo vendor.

Thanks. Please update to a maintained version of kamailio, 5.2.x is already end of life.
Your bug might be already fixed in a newer version. My suggestion would be to use the
latest 5.4.x or 5.5.0 version. Please re-open if the bug is still present there.

Thanks Henning. Does a memory leak with notifier_processes ring a bell by any chance?
The closest thing I've found seems to be the one below, but I don't know if we use
RPC commands. Any suggestions in regards?
