more notes:
When it's in the blocking state and I stop all producers and all consumers so
nothing is hitting the broker then I go to the web admin panel and hit "delete"
to remove the queue I get hit with some errors in my activemq log file in the
data dir
http://pastebin.com/q7mxzGzK
I cannot purge or delete this queue at this time, the browser just hangs.

When I now run bin/activemq stop localhost I'm seeing this in my log file even
though there are no producers or consumers attached to it any longer:
2010-11-12 15:56:40,265 | INFO | The connection to '/10.128.129.20:33830' is
taking a long time to shutdown. |

I'm in a state where I have to kill -9 the process to get the server back.

> Key: AMQ-3034
> URL: https://issues.apache.org/activemq/browse/AMQ-3034
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.5.0
> Environment: ubuntu linux 9.10
> Reporter: Jim Plush
> Priority: Critical
>
> I was seeing odd behavior in production and created a test case around the
> follow issue....
> I have a producer that will attempt to enqueue 1 million messages in a while
> loop. I set the activemq.xml systemUsage settings to the following
> http://pastebin.com/hJXnPHKK very low to reproduce the problem.
> about 1700 messages in I hit the memory and tempUsage limits for
> NON_PERSISTENT messages. My activemq log file now says:
> 2010-11-12 15:25:28,777 | INFO | Usage Manager Temp Store is Full (99% of
> 104857600). Stopping producer (ID:grv-crawl04-35650-1289603606125-0:0:1:1) to
> prevent flooding queue://benchmarks2. See
> http://activemq.apache.org/producer-flow-control.html for more info (blocking
> for: 722s) | org.apache.activemq.broker.region.Queue | ActiveMQ Transport:
> tcp:///10.128.129.20:38430
> which is expected as I just hit flow control. On another machine I fire up a
> consumer to try and dequeue messages while the producer is blocking. It's now
> in a state where I can't enqueue OR dequeue as the consumer times out on the
> .receive(10000) command. The only thing I can do at this point is restart the
> server which loses all the NON_PERSISTENT messages.
> Expected Result:
> Producer would hang when resources are maxed out, fire up a Consumer on
> another machine and it starts to dequeue and free up space, the producer
> slowly starts to enqueue messages again.
> Producer Code: http://pastebin.com/stAN5UJv
> Consumer Code: http://pastebin.com/dWuWWATr
> Version: apache-activemq-5.5-SNAPSHOT
