When I dig more into this it seems to be related to Netty protocol and it= =E2=80=99s 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.
