create a thread dump (kill -QUIT pid) and look for the thread that
hangs.
then fix the bug :-)

  Dear friends,

 When I click on different links or button in my jsp page quickly,
normally
 everythings is ok but sometime
 the tomcat server hang, it can not response to the requests anymore
because
 the
 CPU goes to 100%

 If I publish my website, and when it may happens again the CPU goes to
 100% long enough to break down the CPU. That would be terrible.

 Does anyone know any reason that may cause the CPU runs to 100% like
this?
 Seconds, is there any java method that can take care the CPU and he
 can shut down or start up the tomcat server if needed?

 Many thanks,

 Tu

Hi Leon Rosenberg,

Do you have the sample code like what you show me? I would be much graceful
if you could send me some more code on this matter.

Thank you very much
Tu
