Jitsi server crashes, Sctp send error: : Resource temporarily unavailable

I have installed jitsi server on a dedicated physical server having 64gb ram, 40 cores and 1 tb hard disk using the quick-install guide and using secure domain for authentication with prosody.
The load on this server is very less, 15 gb max ram utilization and less than 20% cpu usage.

It was working smoothly from the last 4 months with more than 100 users daily on more than 10 video conferences daily. It has a peak load of 280 simultaneous users and less than 100 users per conference.

The jitsi server is monitored using grafana.

The server has crashed 3 times in the last one month. The first time the jitsi-videobridge crashed.
It get fixed always after restarting all jitsi related services.

I get repeated warnings in logs before it finally crashes.

It is crashing from the last one month with the following errors:

Main errors in jvb.log before restarting services are:

warning: Couldn’t find packet detail for the seq nums

warning: Unable to find endpoint 69c3ecfc to send EndpointMessage

warning: RTT suspiciously high

warning: negative rtt value

Sctp send error: : Resource temporarily unavailable

Errors now after restarting are:

SEVERE: Could not find data channel

WARNING: Unable to find endpoint 69c3ecfc to send EndpointMessage
