12:57 p.m.
I'm wondering if there is some way to figure out why a message gets to DLQ. Past
experience is you'll see some sort of exception, but in this case messages are going
straight to DLQ after the max size was reached for the queue. First off, the setup is:
- Persisted JMS (MySQL)
- JBoss 3.2
- Queues only
- Max size for queues is five
- Custom DLQ handler
- No MDB timeout/expiration set (to my knowledge)
- MDB configured for five instances max
- Logging has root element pointing to a file, all other severities turned down to TRACE.
What is occurring is 25 messages are sent to a queue name QUEUE.Preprocessor - no problem.
Where the issue comes into play is immediately after five instances fire up two of the
twenty five messages goto DLQ. The five that were/are running complete - no error. After
two goto DLQ, the rest of the messages in the queue appear to processes fine. What I
can't figure out is why the messages goto DLQ in the first place. I have cranked the
logging down (see below snippet) but it doesn't show me how messages sent the
QUEUE.Preprocessor got to DLQ. Past experience shows that normally you'll get some
sort of exception, such as message was corrupt or exception was thrown by the MDB but in
this situation there's nothing in the log file.
Is there any other DLQ interrogation, other than cranking down the logging, that can be
done to see why a message is sent to DLQ? Any help or suggestions is very much
appreciated.
Thanks!
