RE: cpu load 100% on windows 2000 using iis
Sorry about all these postsI could have just been patient and combined them. :0) Did you delete the default contexts? This will cause this problem. Either reinstall them temporarily or look into your config files in tomcat to clear up the issue. Sorry, I don't have time to look them up right now.

RE: cpu load 100% on windows 2000 using iis
Is there a ROOT web app? There is a known bug in 3.2.1 that causes Tomcat to spin in a tight loop if it gets a URL that doesn't map into a servlet *and* the ROOT webapp has been removed. This has been fixed and will appear in Tomcat 3.2.2. Also, be careful using JDK 1.3 if your going to run Tomcat as an NT service. There is a known bug in the JDK that will cause the service to stop when a user logs out. See the archives for this list for lots of discussion on this topic. -Original Message- From: Rui M .

RE: cpu load 100% on windows 2000 using iis
Check your regestry settings. Also: Have you created a virtual directory named "jakarta" in the same folder that the isapi_redirect.dll is located? Mine is physically located in tomcat/bin/Win32/i386/. Have you assigned this directory "execute" access? I think that a small error has crept into your settings. Go over the IIS how to and you will have it fixed in no time. Good luck, Craig I better get back to work!!! -Original Message- From: Rui M .

RE: cpu load 100% on windows 2000 using iis
There is a known issue. It appears that you must insure that Tomcat only operates in a valid context. I have not faced this issue so I don't have any suggestions, however, this may be helpful. Here is a snippet from a past discussion on this issue: /* 6.11 Misconfiguration Can Cause CPU-Bound Loop If you misconfigure Tomcat 3.2 in a way that there is no valid context to handle a request (such as removing the root context and then attempting a request that should be handled by that context), Tomcat will enter a CPU-bound loop instead of responding with a 404 error. */ Hope this helps, Craig -Original Message- From: Rui M .
