Subject Re: High CPU usage impact to log4j

Hi, Andersen

Thanks for your suggestions.

The Visual VM is quite powerful tool, but introduced from JDK6. My issue was
happened at JDK5:(
Besides, before add some algorithm to dump the JVM snapshot, I need to
understand what's the root cause to result in the abnormal behavior of
log4j. The most frustrating thing is that I cannot reproduce the issue with
100% (log4j and kill -3 signal cannot be handled by JVM) :(

Anyway, thank you again.
