james strachan commented on AMQ-1192:
-------------------------------------
I wonder could you try the current 4.1.1 build please? We've fixed a number of issues in the Stomp support to do with handling disconnected stomp consumers which could well fix your issue

> Key: AMQ-1192

> I have added to the STOMP tester so it can take command line args for number of message to be read/sent. Using this the following tests will show the problems
> #1) All messages are lost when a client does STOMP disconnect
> 1.1 start a subscriber to read 5 messages
> ./activemq_tester -d sub -m 5
> 1.2 start a publisher to publish 10 messages
> ./activemq_tester -d pub -m 10
> 1.3 run subscriber again to get the remaining 5 messages
> ./activemq_tester -d sub -m 5
> ---> No messages are available for the second run of the test subscriber. It seems there is no way to shutdown a stomp client without loosing all the messages on that q.
> Output here.
> -bash-2.05b$ ./activemq_tester -d pub -m 10
> Connecting......OK
> Sending connect message.OK
> Reading Response.Response: CONNECTED,
