Hi Nithya I just tried and see the same effect. It doesn't take long the get the perm gen error and seems to be holding onto the whole runtime structure between stop/start. I'll take a look to see if I can see what's going on. In the mean time can you raise a JIRA [1] to track the problem.
Thanks Simon [1] http://issues.apache.org/jira/browse/TUSCANY
