Thanks Johan, I've been through the rtpengine docs and source and can't see any way to disable the RTCP call stat reports. Having said that I'm no longer confident that RTPEngine is the problem - I'm losing memory constantly at a rate of about 130MB/hour at all times, even overnight when we are not seeing many calls. This seems to rule out the RTP reports or anything call load related.
I now wonder if the issue is related to registrations and NAT pings (~3500 registrations). This is the only constant activity on the system overnight (other than OpenSIPs clustering?). NAT pings are enabled for all contacts and many of the handsets are also pinging the server, according to client config. At this time I am not sure where to focus my attention - I've collected some data from my server (version, relevant module configs, memory dump) in the hope that someone might be able to spot a problem with my setup - you can find this at the following link: https://gist.githubusercontent.com/spacetourist/2b880c71eda54bcabf691282d6389209/raw/25c42b90ffa4e592cd761237dffca6f85aabbf4f/gistfile1.txt Please let me know if anything else would be useful. All ideas are very much appreciated, thanks. Callum On Tue, 3 Dec 2019 at 17:31, Johan De Clercq <jo...@democon.be> wrote: > I think you can. Check the documentation of rtpengine on github.
