Scheduler problem

Ok, will try.
In the meantime I have encountered another problem arising in my scheduled task: "OutOfMemory ... Perm Gen"...
As mentioned, the scheduled task is simply copying a fairly large xml file from one location to another via two REST GET and PUT requests.
It seems the problem starts when the file reaches over 100Kb.
Is this a known issue? Can it be fixed?

It's a JVM option, you must add it to wherever you usually put your memory settings for your servlet container. Options include environment variables, catalina.sh, etc.
