Thanks for your inputs.

I have probably attached an incomplete snapshot of the memory
utilization graph. What happens as more time progresses is that the
utilization keeps increasing and the amount of heap that gets
collected keeps decreasing. After some time the system starts doing
Full GCs every second and the application stops responding. The graph
I had previously attached was from an instance where I simulated the
behaviour in our test env but did not wait for the system to fail
over. I stopped the test since I was seeing the same pattern which
ultimately falls over.

I have done a few tests with the JVM argument suggested in the bug
report. The initial tests look good. The memory utilization seems
healthy. The heap, unlike the snapshot I sent previously, seems to get
collected by pretty much the same amount after each Full GC cycle. So
there is no upward trend in the utilization as seen in the previous
Also, yes, ours being a content management application, we have large
body tags. We use several tag libraries that come with the CMS
implementation to fetch content from the CMS.

I will be doing some more thorough tests tomorrow before reaching a conclusion.

Thank you for all your inputs so far. I will share my final findings
in-case they can be useful to someone in the future with a similar
