Hi,
I'm using Apache Tomcat/6.0.24 running on centos and have several times observed a rare issue in which user sessions are "mixed". When this occurs, userA clicks on a link and is provided with userB specific content, content that should only be accessible to userB. When this "mixing" occurs, it seems to affect multiple sessions at the same time, ie userA and userB are not the only ones affected. Restarting tomcat fixed the problem. Does anyone know what causes this or how to prevent it? Thanks, Joel
