As I responded to DeanoUK, who had this same problem, you need to ask about
this in the JBoss Transactions forum, or search that forum to see if DeanoUK
already asked the question there and see what answer he(?) got.

Hello PeterJ,
I have exactly the same issue as you.what I have seen is that there are a lot
of I/O operations under the following path:
"$JBOSS_HOME/server/default/data/tx-object-store/HashedActionStore/defaultStore/StateManager/BasicAction/TwoPhaseCoordinator/AtomicAction".
These I/O operations
JProbe or something like that?
Here's an odd one.

As usual GC ran - at 19:59 which produces a spi
You might ask about these messages in the JBoss Transactions forum.
Looks like the next step is to run with a profiler to find out where your app
is spending its time.

Seeing 99% CPU but not much memory being used + not much GC being performed and
after a while saw these messages (multiple of):

Thanks Peter - I'll do both.

The set of GC output you posted at 9:37 looks good. Earlier, all of your GCs
were full GCs taking around 10 seconds. Now you have minor GCs taking less than
1/10th of a second.
Your post at 10:02 shows that you have overrun the 5GB heap you set. Note the
heap sizes both before and after the col
And now this, only some minutes after a restart:

Ok so we've had this running for around 12 hours+ and we're seeing similar
issues.

You might have to try several heap settings, and use -XX:+PrintHeapAtGC to get
the GC details, which you should graph and then analyze. That should tell you
what to set the heap to.
Also, set -XX:NewSize the same as MaxNewSize.

PeterJ, I very much appreciate your response. I think you've hit the nail on
the head too.
I'll ensure we do this on the server ASAP and see what we results occur.
What I don't really understand, is that we were having similar problems when
the MaxNewSize was at default, which I believe is 32mb
With those heap setting, the JVM will always do a full collection, which you
noticed. The reason why: the JVM assumes the worst - that all objects in the
young generation will survive the collection. Thus all 3GB of the young gen
objects will survive, but according to your settings there is only
12 matches
