Tomcat Serving another URL

I have about 10 sites running in a single tomcat instance. I 开发者_开发技巧have been experiencing this issue for over a month now.

Randomly, tomcat serves a content from other webapps. For example if i am requesting for index.jsp it serves some design png from another web application.

It is hard to reproduce the problem, but i have experienced this very often.

I tried increasing the number of worker thread, did not help. I have a shared tomcatThreadPool between the webapps, dont know if that might be a problem.

Any pointer would be very much appreciated. Please suggest, shall i migrate to Jetty instead.

Thank you

Look in the context.xml and web.xml if you have right specification of context, filter, etc. - problem like that have been shown in version 4.X, so try latest version as BalusC says.
