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?

Re: OutOfMemoryError: PermGen space when running on jBoss
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.

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?

Hi Claude, Claude Vedovini schrieb: This option does not appear in my VM's help (java -X) but I will give it a try! Its an extended option, which is so extended, that it does not even appear on -X ;-) By the way, do you know where I can find what is the available context in a script, beyond currentNode? Have a look on our wiki at [1] (this page should probably go to the main site...)

Its an extended option, which is so extended, that it does not even appear on -X ;-) 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 :) By the way, do you know where I can find what is the available context in a script, beyond currentNode? Have a look on our wiki at [1] (this page should probably go to the main site...) [1] http://cwiki.apache.org/SLING/scripting-variables.html 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...
