Matt Pavlovich commented on AMQ-9748:
-------------------------------------

[~lionel.cons] Have you adjusted the OS TCP socket settings to lower the 
TIME_WAIT?

Do you see the CurrentConnectionsCount go _down_? Trying to determine if it is 
a runaway leak of the count or a slow-to-decrement type issue

> Incorrect CurrentConnectionsCount metric

>                 Key: AMQ-9748
>                 URL: https://issues.apache.org/jira/browse/AMQ-9748
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: JMX
>    Affects Versions: 6.1.5
>            Reporter: Lionel Cons
>            Assignee: Jean-Baptiste Onofré
>            Priority: Major
>             Fix For: 6.1.9, 6.2.1

> In some cases, the current number of connections (as reported via JMX) is not 
> correct.
> We did not find any easy way to reproduce the problem. It seems to happen 
> when there are some rapid re-connections from the client side. Then the 
> counter stays wrong (too high) until the broker is restarted.
> Here is for instance what can currently be seen on one broker:
> {code:java}
> # jolokia http://localhost:6105/api/jolokia read 
> 'org.apache.activemq:type=Broker,brokerName=*' CurrentConnectionsCount
> {"org.apache.activemq:brokerName=foo.acme.org,type=Broker":{"CurrentConnectionsCount":4955}}
> # netstat --tcp -n | grep ESTABLISHED | wc -l
> 63
> {code}
> So ActiveMQ reports 4955 active/current connections but the OS (Linux here) 
> strongly disagrees.
