I am going to guess that some policy in Windows rejects the high volume of logons, too many connections or something of that kind. It's most likely not a Tomcat problem. Andre suggestions are pretty good in terms of isolating it. I would start by stressing IIS alone with a static page in it.
Since you're running on Windows, you might as well get rid of IIS and replace it with a Waffle filter - http://waffle.codeplex.com. dB. @ dblock.org Moscow|Geneva|Seattle|New York -----Original Message----- From: Yun Feng Chua [mailto:yf_c...@hotmail.com] Sent: Wednesday, July 21, 2010 3:07 AM To: users@tomcat.apache.org Subject: isapi_redirect.dll fail in SSO on high cpu load Hi, Currently using Tomcat 5.5 and isapi_redirect.dll 1.2.14 in IIS 6.0 Configure with IIS integrated authentication for SSO. Notice that under high cpu load in the server, 100% util, the website prompt for authentication. When the cpu load subsided, the SSO is working. Any ideas why it prompt for authentication under heavy cpu load? thank you yun feng, chua --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
