To: Henning Westerholt <hw(a)skalatan.de>
Thanks for your reply. Here's what has come up after a few hours:
It seems to me htable is the culprit? Are you seeing anything different? 54
has been running for 77020 seconds, 55 for 28521 (significantly less).
I'm going to turn it off until we figure something out...

please report more details. If you can point to a particular module, you

I'm still investigating the (most likely non-kamailio-related) memory leak
of my previous message to the list, there have been no developments so far.
I'll update if anything changes.
This concerns a new finding which seems to affect kamailio 5.5.x. I have
two kamailio instances receiving the same traffic via round-robin. I
upgraded only one of them to 5.5.1 and left the other to 5.4.6 as I feared
of any issues arising. I was lucky to do so, because with identical
configuration, 5.5.x seems to run out of SHM very quickly. Here are links
to graphs produced by our monitoring system:
Old kamailio (no memory leak): https://pasteboard.co/K8fVBiD.png
New kamailio (possible leak): https://pasteboard.co/K8fVS9N.png
The configuration uses mtree, htable, vars and vns extensively. Has anyone
come across anything similar? Let me know if I can provide any further
information to help disect this. Thanks!
