Several have reported intermittent hangs in GF lately that shows a
deadlock in the logging code. After some investigation Dhiru found that
there is a bug in the JDK and has been fixed. Please check the version
of the JDK you are running and upgrade if needed.

>Looks like this is caused by a JDK bug:

>This was fixed JDK 6u11. We were using JDK 6u6 on hudson.
