## B.2 OutOfMemoryError: PermGen space running on Sun VM

As a result of Sun Java bug 4957990, the Virgo Web Server may consume more PermGen space than expected when running with the server HotSpot compiler. This problem may be resolved by configuring the `JAVA_OPTS` environment variable to specify an increased `MaxPermSize`, for example `-XX:MaxPermSize=128M`.
