Producers hang when broker is fubar
-----------------------------------
Key: AMQ-1625
URL: https://issues.apache.org/activemq/browse/AMQ-1625
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.1.0
Environment: SNAPSHOT build from 1/16/08
Reporter: peter royal
Attachments: hung producers.log
see attached log.
in a nutshell,
Transport.request(Object command) is dangerous, and shouldn't be used.
Transport.request(Object command, int timeout) should be used instead.
something happened to my broker (don't know what yet), and it caused the
producer to hang as seen. then since the session is shared, a bunch of other
threads blocked as well. if the request on the transport had a timeout (this is
to catch failure scenarios, so something that's not expected to reasonably
happen), things would have errored out rather than building waiting threads.
if it is amiable, i can produce a patch that will remove the non-timeout'd
version of Transport.request() and use the version with a timeout everywhere.
