Subject [jira] Updated: (AMQ-2186) Number of messages when browsing queue is different to "Number Of Pending Messages" in queue list
Date Fri, 27 Mar 2009 04:44:42 GMT

Loc Truong updated AMQ-2186:
----------------------------

      Component/s:     (was: Broker)
                   Message Store
    Fix Version/s:     (was: 5.2.0)
      Description: 
1. The Queues list displays a number, "Number Of Pending Messages" for like 1000.
2. When clicking on that queue, the number of message (total of all rows) is smaller than
1000.

Actually the #2 always displays a very small number of messages which is not more than 100
although the number on the list keep increasing to like forever.

The problem doesn't happen when ActiveMQ starts but after one to a few hours instead. At the
moment the only way to resolve this at our end is to restart the AMQ.

  was:
When you "purge" queue from web admin console, it zeroes queue message
counter. But if you have an active consumer at that time which
pre-fetched messages than your consumer will keep sending ack as it
process messages from its buffer. ActiveMQ will keep decrement counter
upon receiving each ack. So when consumer is done queue will show
MINUS<consumer buffer size>.



      Environment: CentOS 5.2 64bit  (was: Found on Windows but reproduced under Linux)
       Regression:   (was: [Regression])
