Edwin Wang commented on AMQ-5338:
---------------------------------
I have use JConsole to monitor the OOM problem and found for 5.10, something in
"tenured gen" can not got released after GC. And the "tenured gen" will grow up
and up and finally caused the problem. (Actually, each time after the full GC
performed, the tenured gen can release some memory but it still keep going up)
Again, the GC situation is correct in 5.5.1
> Run into Memory Leak problem after upgrade from 5.5.1 to 5.10

> Key: AMQ-5338
> URL: https://issues.apache.org/jira/browse/AMQ-5338
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.9.0, 5.10.0
> Environment: Windows 2012 R2, JDK 1.7.40, CPU I5, Memory 8G
> Reporter: Edwin Wang
>
> Our production environment has used ActiveMQ 5.5.1 for a long time and it
> works well. Recently we decided to verify ActiveMQ 5.10 for prepared for
> upgrade. However, after we upgrade the test environment to 5.10, the MQ is
> easy ran into out of memory every 7-10 days.
> In order to compare the two, I use the same environment and same
> configuration for both 5.5.1 and 5.10.0. Finally, 5.10.0 ran into out of
> memory while 5.5.1 works well.
> It looks like a bug for 5.10.
