"OutOfMemoryError: PermGen space" when running on jBoss
Hi all,
I am running Sling under jBoss and I am not able to keep the server
alive for more than 10mn (30s when using a webdav client) because I
get "OutOfMemoryError: PermGen space" errors, even tho the max heap
size is set to be at 2Go.
I searched through the mailing-list archives but the only results are
related to the building of Sling.
On Google, results are suggesting issues with webapp reloading
features, but that's not happening here.
Any hint?
Thanks,
Claude Vedovini

Hence the double X I guess...
It seems to be working fine now (no failure since 30min) but I am
going to let it run on its own for a while :)

I should have found that myself, sorry.
I must admit that once I have been crawling in the docs for 2 or 3
days, not finding what I am looking for, I start to ignore it
altogether :(
one last question, about sling.home...
what is my best option here (in a container) to configure it to the
folder I want?
This page http://cwiki.apache.org/SLING/configuration.html leaves me
with little hope beyond manually tweaking the jar...

Its an extended option, which is so extended, that it does not even
appear on -X ;-)

Have a look on our wiki at [1] (this page should probably go to the main
site...)

Hi Max,
This option does not appear in my VM's help (java -X) but I will give it a try!
By the way, do you know where I can find what is the available context
in a script, beyond "currentNode"?
Thx,
Claude

Hi Claude,
raising the heap size does not help here, since this does not
(generally) enlarge the PermGen space. The PermGen space is used amongst
other things (very old objects) to store the class objects. If this
space fills up, the VM has lost ...
So, provided you are running a Sun VM, you might consider setting the
-XX:MaxPermSize command line option to a higher value than the default.
See also [1] for more info.
Hope this helps.
