Doc Type:	Known Issue
Doc Text:	Cause: The plus/minus operations of the mod_cluster connected count (a proxy_worker's busy attribute) aren't atomic because that would have some performance impact. Consequence: The mod_cluster connected count shows improper inflation. Workaround (if any): None Result: The mod_cluster connected count can be inaccurate. With load stopped, non-zero values have still been seen through the mod_cluster-manager page and INFO MCMP responses.

Comment 1 JBoss JIRA Server 2014-07-08 15:03:47 EDT

Aaron Ogburn <aogburn@redhat.com> updated the status of jira MODCLUSTER-416 to Reopened

Comment 2 Jean-frederic Clere 2014-11-07 05:54:57 EST

I think it should be documented as a known as the fix only improves the situation.

Comment 3 Michal Karm Babacek 2015-01-20 10:19:46 EST

https://bugzilla.redhat.com/show_bug.cgi?id=1018705#c16

I think we should decide what to do with BZ 1018705 and BZ 1110515 for good.

@JFC Regarding comment 2, do I get it right that we should close & document both of them?

Comment 4 Jean-frederic Clere 2015-01-20 11:44:59 EST

@MICHAL yes close & document.
