Description

If a call is purged or canceled we try to skip the reply from the server, but we read the wrong number of bytes so we corrupt the tcp channel. It's hidden as it triggers retry and so on, but it's bad for performances obviously.

It happens with cell blocks.

ram_krish_86, [e-mail], you know this part better than me, do you agree with the analysis and the patch?

The changes in rpcServer are not fully related: as the client close the connections in such situation, I observed both ClosedChannelException and CancelledKeyException.
