Gary Tully commented on AMQ-1940: --------------------------------- @Sergey - can you make a junit test case that can reproduce - peek at the activemq-camel module if you need to use camel routes > Negative queue size (reproducible) > ---------------------------------- > > Key: AMQ-1940 > URL: https://issues.apache.org/jira/browse/AMQ-1940 > Project: ActiveMQ > Issue Type: Bug > Components: Broker > Affects Versions: 5.2.0 > Environment: Found on Windows but reproduced under Linux > Reporter: Vadim Chekan > Assignee: Rob Davies > Priority: Critical > Fix For: 5.3.0 > > Attachments: Main.java, Picture 6.png, QueuePurgeTest.java.diff.txt > > > 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>. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
