Currently our production is running with 3.5.5 and it will take time to move to 3.6.1.
When I dig more into this it seems to be related to Netty protocol and it’s limitation. The system is stable when I fail back to NIO and without SSL. As soon as I turned on Netty we are seeing sessions getting throttled which in turn sometimes throttles the ping request too from clients. I believe we should get an option to configure Netty in such a way that ping commands are never throttled.
