We're having a problem with garbage collection as described here:

We are going to try an upgrade to JRE 6u24 soon, but reading the release
notes for each of the versions since 6u20, I don't have much hope of
this upgrade fixing the problem.
I have searched a bit on the Java bugs database and I've come across
something that looks similar to the problem I am experiencing:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6692906, but I'm not
convinced this is exactly the same issue. This bug it seems will be
fixed in 6u25 (which I've read will be released late March or early April).
The reason I'm leaning towards thinking this is a JVM bug is the fact
that the JVM can stay in the hung state (as described on the forum) for
2+ hours until we kill the process.
I was hoping to get an idea about this from the source :), so any hints
will be greatly appreciated.
