Hey Matt,
Thanks for the detailed information! Can you log this in JIRA? The
Beehive project URL is https://issues.apache.org/jira/browse/BEEHIVE.
You may have to create a log in.
Thanks again. Appreciate the help.
Kind regards,
Carlin

FlowController.incrementRequestCount() and
FlowController.decrementRequestCount() access the variables
_requestCount and _maxConcurrentRequestCount outside of any synchronized
block. This makes it possible to _requestCount, especially on a
multi-processor machine. The subtlety of this bug is that
--_requestCount and ++_requestCount look atomic, but they are not.
In particular, we have an action that returns images. Since some pages
contain many images, this controller can be hit my many requests
concurrently from the same session. We hit the decrementRequestCount()
assert quite frequently in production.
assert _requestCount > 0 : request.getRequestURI();
Thanks,
Matt
