BTW, did you try the -Xincgc option for continuous GC on Sun's JVM? That would probably give you the same results you were seeing in JRockit. Depending on how you configure each you may not be looking at an apples to apples comparison.

"That's a pretty nice review..."
Yes, in fact I expected to see a link to the storefront that would net him
some micropayments: a nickel per view:) My only concern is that they are now under
BEA's umbrella so the temptation to enhance or hobble when running or not running in
weblogic is there.

That's a pretty nice review. Does anyone else use JRocket on Linux?
What are there experiences?

After testing a while with several VMs We found out that BEAs
Jrockit is by
far the best VM for usage with JBoss (Of course this is what
we found out
for our Tests and is only an oppinion, so please don't shout
too loud). Even
if it does cost a little for a production licence, the
performance and
stability it provides is worth much more.
Using this VM we were able to run the SPECjAppServer2002
benchmark in a 9
Node cluster under full load for over one hour. This is much
more than we
could achieve with for example the Sun VM with 35min. This
indicates that it
seems to handle the usual VM-trash a lot better. We could even
monitor
absolutely constant Memory usage - a thing we could not say
for the Sun VM.
I would absolutely recomend trying this.
Our Systems were all SuSE based Linux System on AMD machines.

hi peter,
i run jboss in the same exactly environment, but i don't seem
to be
running into these problems.
we found the ibm jvm to be the best for our scenario...maybe
you should
take a look at it.

We're using JBoss3.2.1 with Jetty on RedHat 9 with
Suns 1.4.2_01 vm.
We have a pretty heavy load.
After roughly a week many of the boxes start to
experience weird
problems where JBoss is unable to get what looks to be
socket
connections. In some cases, we cannot contact our
mailserver, in other
cases we cannot contact our database; in the latest
case we're unable
to get a connection to the local jndi server
(localhost:1099).
Sometimes a simple restart of jboss will sometimes
solves the
problems, othertimes we have to restart linux. The
times of the
crashes are roughly 4am and sometimes 6am, so it's
likely caused by a
cron job running at those times, which we're currently
looking into.
Has anyone experienced similar problems?
