Hi:

I have an Java Application which connects with MQSeries Server. All enviroment is stable and works well. In Friday, TCP/IP connection with Remote MQSeries was with troubles and Sender Channels was instable.

So, Java getMessage() still locked and it tried to get COD/COA messages for report queue. We use one exclusive queue for these reports. No MQI error
Exception was trought to Java and no errors appears in AMQERR01.LOG (except logs for Sender Channel, of course). In MQExplorer I could see 30 messages in queue, and two messages are add when one new message was sent (normal behavior).

In final of day, when connections with remote MQ was re-stablished, messages still locked in queue. IÂ´ve restarted application e rebooted server of this app, but didÂ´nt worked. So we made same thing in MQSeries server (restart MQ app and server), but messages still frozen in queue.

So, IÂ´ve cleared report queue e tried to send new messages (50). The report queue received 100 messages (50 COA and 50 COD), which was fastly got from queue to app.

Anyone may explain this behavior? Why reboot of app e MQ side didnÂ´t work? Is possible that first message in Queue may corrupted causing lock of get() function?
