Unable to create media pipeline for session

Hello,

Our OV 2.17.0 on premises (Ubuntu 18 server) works well for a while (a day or two), then stop working. I can create a new session, etc using REST, but any attempt to join newly created session failed with the server event “unable to create media pipeline for session XXX”. Restart the server helps. Then it works for another 2 days and everything repeats.

I also see that all old sessions stay in memory (I have 10-11 sessions after the crash), although it’s obvious that at that moment no connections were made to them for hours. I expected based on the another thread in this forum, that old sessions should be auto-destroyed. Not sure if that connected to the issue I’m facing.

Please find the logs of both Kurento and OpenVidu here: OV LOGS - Google Drive

Logs were recorded after the moment when server was failed for a while, before the restart.

Any help would be appreciated.

Mike
