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,

Hello,

can you check the expires column in presentity table. The issue might be accumulation of too many dialog-info documents, due to large expires interval, taken from the default lifetime of the dialog. You can change that with:

Hello,

which memory is increasing? shared or private memory? or is system memory?

Cheers,

Daniel

Hi Juha and all.

I understand that and that is what the RFC says. It seems pua module does that right. Although something is clearly not right in my production environment because kamailio memory consumption still grows pretty fast. Kamailio memory usage starts in ~500MB and after ~24H kamailio is using ~3GB. If I disable kamailio from listening on the localhost(127.0.0.1) where pua is generating the SIP Publishes kamailio just keeps around the ~500MB all the time.

This is a small production environment with 70 extensions with Yealink phones.

Any ideas on how to chase down this memory leak? Should I open a git issue for this one?

when your application issues initial publish request, it does so without
SIP-If-Match header. 200 ok from presence server then contains an etag
in SIP-ETag header. when your application refreshes the publish, it must
place this etag in SIP-If-Match header to prevent presence server from
creating a new publication.

for subscribes, your application must place in re-subscribe the
same event header id param as the previous one had in order for the
presence server to know that subscribe was not a new subscription.
