Nx server, mediaserver unstable if two Nx servers are merged
AnsweredFail rate: 100%
System version: v4.2
OS: Ubuntu 20.0.4
What we faced:
Even if Connection established successfully, all registered camera image is not visible.
Observation :
Running out of OS resources because of failure to close TCP(TLS) connection. TCP connection from Nx Server#1 to Nx Server#2 is established every few seconds. However, TCP sockets are not closed (remained as CLOSE_WAIT state). Thus, in the end, kernel resources (socket buffer) were exhausted.
Question :
Is this a known issue?
And If yes, how to avoid this?
If not, we need a hint to identify the root cause.
