Big problem. Transport failed: Async Exception Handler

[James Green <ja...@gmail.com>]

One of our staff just reported that a queue on our "hub" machine was not
being read any more.

Checking the logs of the PHP app we're getting:

exception 'StompException' with message 'Unexpected EOF while reading from
socket'

Inside AMQ (5.5.0/Linux and configured with ACTIVEMQ_OPTS_MEMORY="-Xms512M
-Xmx512M") all I get is:

2011-05-24 09:44:24,918 | INFO  | Transport failed: java.io.IOException:
java.io.EOFException |
org.apache.activemq.broker.TransportConnection.Transport | Async Exception
Handler

Nothing else.

I have now restarted AMQ but still the problem continues. The queue
concerned, which was over 30k messages now stands around 29k (non-persistent
messages have gone). Now the first entry in the queue I cannot get to from
the web console:

Other messages I can browse to. I cannot even delete this 1st message
listed. I have now had to purge the queue, obviously losing those 29k
messages.

Is this already listed as a bug?

Thanks,

James
