Mike, Thanks again for your advice!
I have never used other JDK's, will all the methods and the entire API be the same or should we do extensive testing before trying the new JDK with our applications? Either way, we'll download and try it immediately and see what happens.

Hmmm, well, first things first, the Sun JDK isn't so good from what I understand. From what I've read it seems like the IBM one was nearly the best, but there's some better ones out there. You might try one of two things: either switch to the IBM jdk (1.3.x) or try upgrading to the current Sun JDK 1.4.x. See if that helps things any. Once the new JDK's are installed it should be a simple matter of changing your JAVA_HOME or in my case changing a symbolic link. --mikej -=----- mike jackson [EMAIL PROTECTED] > -----Original Message----- > From: Brandon Cruz [mailto:[EMAIL PROTECTED]] > Sent: Monday, September 30, 2002 2:09 PM > To: Tomcat Users List > Subject: RE: Can someone PLEASE tell me why tomcat uses so much CPU??? > > > Mike, > > Thanks for answering. > > I'm using Sun's JDK 1.3.1_01. > > We have been running this in production for over year and I think we have > always had the problem.
