RE: CPU goes to 100%
Thanks Joe, I will try to do this. I will tell you if it works. -Original Message- From: Joe Sutherland (UKI) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 05, 2001 11:21 AM To: '[EMAIL PROTECTED]' Subject: RE: CPU goes to 100% Hi Anand, Just a suggestion check to see that you are clearing memory (=nothing) after instantiating objects, otherwise 2000/NT keeps hold of it and only releases it it after a refualt period (say 30 mins...) - and this can build quite quickly after each user leaves the app. I dont know that much yet about the JSP environment, just learning, but this is common problem on similar developments with VB DLL's when they have not been written properly (where the object has been used in the page and not set it to 'nothing' when you present the page to the user...) Hope this is a help.

It is running on Windows 2000 server and we are using Sun's Java 1.3. Most of the day the CPU stays at 0%, but for some reason every afternoon it goes to 100% and application slows down to a crawl. At the end of each jsp file, we do some garbage collection, but it still does not seem to help. Does anyone have any ideas?

Re: Tomcat job
Hi Jeremy, I am also getting the same 100% usage too. I am using Windows2000, Tomcat 3.2.1, java 1.3. Anyone has any ideas?
