## B.3 OutOfMemoryError: PermGen Space Running on Sun JVM

As a result of Sun Java bug 4957990, the Virgo 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`.
