It's a bit unusual to run out of PermGen space after a while like this, but if you're very close to the limit to start with, it's still within the realm of the possible. Try increasing the PermGen space limit by, say, 25-50% and see if the problem reoccurs. There's no dynamic class loading in Ode so I'd be surprised if there was a class leak, although even the use of regular Java Strings have been known to cause leaks<http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=1cf84381aec1d4c1375a060ca38b?bug_id=4513622>too.
