You can play around with these settings: http://stackoverflow.com/questions/8356416/xxmaxpermsize-with-or-without-xxpermsize
We ran into the same problem at my last company. Turns out it had to do with the way Hive Server was loading jars, IIRC it was because Hive was loading the same class definitions for every request, so they built up over time. You should profile your application (examine its memory) to see if this is the same issue (probably is).
