Are you using some "non-standard" configuration, e.g. virtual host or remote or slow filesystem? If so, please see bug 229903 comment 5. Otherwise, can you reproduce the bug? Could you generate and attach thread dump or profiler snaphost? Thank you. *** This bug has been marked as a duplicate of bug 229903 ***
