Hi,
I also see the APR JMX memory leak with following APR Connector config
<Connector port="30011"
URIEncoding="UTF-8"
useExecutor="false"
minSpareThreads="150"
maxSpareThreads="150"
maxThreads="150"
connectionTimeout="300000"
protocol="org.apache.coyote.http11.Http11AprProtocol"/>
pollerSize="1024" />
Regards
Peter Roßbach

much appreciated, I'm still working on the "deregistering" of the

Originally, the purpose of the JMX stuff was to provide thread
monitoring. Now that the processors are not tied to threads
anymore, it becomes a bit useless IMO. Normally, Java 5+ provides
JMX monitoring of threads already, but of course the Tomcat JMX
does provide a little more data (that may or may not be worth
keeping).
I've done the fix for the NIO connector. I believe I have been able
to take care of all the problems.
In the NIO protocol, I simply got rid of the thread local, and
replaced it with a queue.
This queue is able to deregister objects, should it be needed.
Only time they are deregistered, is if they number exceed the
processorCache=<int value for max number> in the NIO <Connector>
element.
The memory leak exists in the APR and JIO connector, when and only
when they use the shared <Executor> and the Executor has a
minSpareThreads<maxThreads.
Since these connectors do not use an executor by default, I'd like
to get some feedback if these two need to get fixed for the
upcoming release.
If we are to proceed with the release without fixing these, I would
simply note it in the release notes, that to use an executor, use
the workaround.
I'm open to suggestions...and once again...thanks for your patience
(especially since it's me that want this new release)
