Hello,
We are using WCS and WebRTC in production.
Every 8-9 days, Flashphoner freeze and refuse new connections.
In the log, we are seeing a LOT of :
I attached our Grafana Dashboards, we are not seeing saturation on media or wcs_agent ports during the incident (20H-21H40 on the graph).
We are using an old version (5.2.1794) with the configuration below.
We are going to upgrade to the latest version and increase the media_port range to 30000-32500.
We looked at this issue https://forum.flashphoner.com/threads/com-flashphoner-server-g-a-e-no-free-ports-available.11295/ but we don't have this much usage. Only 10-30 users and 100 streams maximum.
Are you aware of a bug in this version? (we found no trace of a fix in the release note)
Do you think it could be a configuration issue or something else? Thanks !
I did a netstat -laputen on the virtual machine during the incident, and there was only a few ESTABLISHED and TIME_WAIT connections. As you can see on the dashboard, metrics show a lot of available ports. Incident occurred two time in a row already. Very strange.
