None of these are leaks; they are purely background threads, that are
used to support non-blocking updates of various things.  I believe
they have the daemon bit set; I'll check on that.  If they do,
however, then the above messages are the bug.

hi,
sorry for reviving this thread.
i am to getting error of memory leak when i shutdown ofbiz application.

i googled and get this reference.
http://www.coderanch.com/t/498919/Tomcat/Memory-Leak-repeat-deploy-undeploy
look at replied #3

i have tried to run ant clean-catalina
after that, i start up ofbiz, login into the catalog manager, then logout.
and then stop ofbiz

the error about the memory leak still appear.

does anyone manage to resolve this memory leak error ?

I believe we have no longer these errors messages in trunk, which version are you using?
You might be interested by a recent improvements I committed, not sure it will help you much though.
http://svn.apache.org/viewvc?view=revision&revision=r1542795
Also not sure you are facing a real problem, did you profile?

Jacques
