Howdy, There's no "patch" for this "issue" and AFAIK no one is actively working in this area. That's because it's not really a log4j bug.

Thanks Elias. I'll comment the log statements in synchronized methods and try. Is there any log4j patch for this? I can see some one working on fixing it.

I suggest you don't do any sort of logging while holding any locks.
