[SR-Users] Possible memory leak dealing with presence in kamailio

[Nuno Reis]

Hi Daniel.
Thank you for your suggestion and feedback on this.
I've tried that already and here's what I've found after 15h on a running
kamailio:

All records in pua and presentity DB tables are gone by the end of the day,
so the expire time seems to be working.
I still see system memory growing and not being released again.
You can find attached (tar.gz) various dumps of pkgstats and shmem usage.
The number after the 'underscore' in file names corresponds to system
memory allocation in kamailio at the various timestamps. The earlier
timestamp corresponds to minute 1.
So I started with 638632kb system mem allocation and I'm now with 1086548kb
being used after 15 hours.

I'll continue to investigate the issue but if you have any other
suggestions on how to tackle this, I'm of course available to test those.
Looking forward to hear from you.

Best Regards,
