Information on the "500 Servlet Exception" error message
From EtherWiki
The Resin application server, used by LunarPages hosting, will sometimes report the following error:
500 Servlet Exception [java.lang.OutOfMemoryError: PermGen space]]
According to Resin's web site [1] this will generally appear when new code is uploaded. It usually takes 15-20 minutes to clear up after the server deploys the new code.
