Hello FS Experts


I had posted this Q earlier... posting it again with more details ...


I have a FS to which two separate external SBCs connect and uses TLS


Intermittently the FS does not respond to TLS client_hello - because of this, we see that sometimes one of the external SBC is not connected at all..


I was able to reproduce this with debug logging enabled and below is the snippet of the same

In the above snippet, you can see that the clietn_hello is received ... [highlighted]


Please let me know if any of you have encountered such an issue and what the fix is
