Robbie Gemmell updated QPID-2872:
---------------------------------
Status: Ready To Review (was: In Progress)
> Java broker incorrectly indicates it supports sending 0-10 heartbeats when it
> currently does not

>
> A blocking recieve() with the java 0-10 client connected to the Java broker
> was observed to fail because the client connection timed out:

> Examining the client logs reveals this to be because the client had
> heartbeating enabled despite the fact the Java broker is currently unable to
> generate 0-10 heartbeats (as its implementation is largely based on the
> client, and the client can only seems able to reflect heartbeats it recieves,
> not generate them at will, meaning neither client or server can initiate the
> heartbeating currently. See QPID-2796). As a result, the client timed the
> socket out after the defaulted 120sec heartbeat delay. The client default was
> allowed to be used because the broker innaccurately indicated it could
> support >0sec heartbeats by sending the wrong heartbeatMax value:
> IoReceiver - localhost/127.0.0.1:5672 2010-09-19 16:21:52,980 DEBUG
> [apache.qpid.transport.Connection] RECV: [conn:e32802] ch=0
> ConnectionTune(channelMax=65535, maxFrameSize=65535, hear
> tbeatMin=0, heartbeatMax=65535)
> IoReceiver - localhost/127.0.0.1:5672 2010-09-19 16:21:52,980 DEBUG
> [apache.qpid.transport.Connection] SEND: [conn:e32802] ch=0
> ConnectionTuneOk(channelMax=65535, maxFrameSize=65535, he
> artbeat=120)
> Until QPID-2796 is fixed, the broker should not indicate it supports
> heartbeating.
