The JVM may use the memory for something else when the queue is emptied. But the OS may not give the memory to some other application until the JVM releases it. I don't know the conditions for the JVM to release memory back to the OS, but AFAIK there is no way to this programatically. (Some brief info here: http://java.sun.com/j2se/1.5.0/docs/guide/management/jconsole.html#memory) There is also an enhancement request on this here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6197676 >In my opinion, OS memory should restored to normal without exiting >the application. Well. Who is to decide what is "normal"? How long will it take until the memory is neede by the JVM again? Having to re-allocate it from the OS will affect performance. >Mattias Jiderhamn-4 wrote: > > > > At 2006-09-25 11:11, chuboz wrote: > >>Is there any bug on JMS implementation on Resin pro 3.0.12 ? > > > > Is there any software you dare say it does not contain any bugs...? > > > > > >>I tried to use JMS MemoryQueue on Resin and it decrease my memory > >>eventhough I have already emptied all my messages from queue. > > > > What do you mean by "my memory"? > > As the MemoryQueue needs more memory, the JVM will allocate more > > memory from the OS.

Re: [Resin-interest] Resin JMS
Correct me if i'm wrong, You mean that eventhough we fetch messages from queue, we won't get the memory back? In my opinion, OS memory should restored to normal without exiting the application. Or my concept is wrong? Please enlight me. Thanks.

What do you mean by "my memory"? As the MemoryQueue needs more memory, the JVM will allocate more memory from the OS. When the queue is emptied, the JVM will probably hold on to the memory. That is, the memory may be reused by other parts of your application, but it will not be returned to the OS. ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] Resin JMS
Friends, Is there any bug on JMS implementation on Resin pro 3.0.12 ? I tried to use JMS MemoryQueue on Resin and it decrease my memory eventhough I have already emptied all my messages from queue. For bulk transactions, I used ObjectMessage and during transactions, I never close session or connection. Any help is appreciated.
