Vahram Aharonyan commented on GEODE-3637:
-----------------------------------------
Udo,
Is there a possibility that after moving registerClient from Acceptor thread to
ServerConnection.run it is ServerConnection that will stack forever on socket
read once the socket closes on other side and notification of that gets lost
due to packet drop?
Also initializeClientNofication is being called in ServerConnection only for
Selector case, in Acceptor thread that was generic and was not depending on
Selector mode. Is this expected change?
Thanks,
Vahram.

> Project: Geode
> Issue Type: Bug
> Components: client/server
> Affects Versions: 1.1.0, 1.2.0
> Reporter: Vahram Aharonyan
> Assignee: Udo Kohlmeyer
> Priority: Critical
>
> org.apache.geode.internal.net.SocketCreator#configureClientSSLSocket timeout
> for Socket is being configured before starting SSL handshake only if passed
> "timeout" argument is larger than 0.
> Having sslSocket.startHandshake issued without setting timeout can result to
> the blocking of caller thread as in GEODE-2898, GEODE-3023.
> Below is the example of Handshaker thread stack-trace that got stacked:
