Alfresco crash while uploading documents

fluca1978 — Mon, 04 Apr 2011 08:56:20 GMT

Hi all,I'm running 3.2 ce on a dedicated machine and while uploading documents thru web services the machine gets "crazy" (I mean the java process serving Tomcat consumes the 100% of the cpu and the web client got a socket i/o error). The stack trace found in the tomcat logs was:10:47:57,401 User:sm

Yes you are out of "PermGen" space.

Uhm…but the PermGen space should be filled with classes metadata, that is it should not be filled if the running code base is constant along time, right? In my alfresco instance I'm running only an application with web services deployed as a Tomcat war. This means that the code base is not changing along time, so the PermGen should not be filled as the application runs, right?
Moreover I found that executing the uploading with a block of 2000 documents the system works fine, while with a single chunk of 12000 produces the out of memory. So the only thing changing is the size of uploading data, not the running code. Could it be a leak in the Alfresco itself? Or am I getting all wrong here and don't get the problem?

Just for the record: my maxPermSize is set to 128 MB.

Thanks.

If you have 2GB allocated to Alfresco then a permgen of 128M is far too small. At least double it.

Its not worth going into details while your system is mis-configured.

Ok, thanks, I'll double it.
I was using the configuration explained here as starting point http://wiki.alfresco.com/wiki/JVM_Tuning.

Thanks

After having doubled the size of PermGen I've noted that also upload times have doubled. Is this a direct consequence of such configuration parameter?
