> Using  STOMP C client subscribed in client ack mode
> A) send 20 messages into a Q
> B) startup slow reader, read 5 messages and control-C without allowing client to send DISCONNECT
> C) restart a reader (or more readers if desired)
> D) the remaining 15 messages are still present but none will be delivered to the STOMP clients until at least 1 new message is written into the Q.
> So no loss of messages under these conditions but Q is effectively stalled until a new message is written in.
> ------ copy of Hiram's comments from AMQ-1192 ------------
> I think this is due to the socket being killed but the server side not noticing. But it will notice once it tries to send it a message, so the it shutdown the dead socket and redelivers all messages queued for the client. On some OSes the TCP timeout interval can be tweaked. Otherwise, keep alive packets would need to be periodically transmitted in Stomp so that the server could detect a dead client sooner. Keep alives have not been added to Stomp yet.. but could be in a future version.
