Catalina.out file for the Smarts NCM installation located in /usr/tomcat/APACHE-TOMCAT-CURRENT_VERSION\logs contains the following error:

SEVERE: IOException while loading persisted sessions: java.io.EOFException

Environment

VMware Smart Assurance - NCM

Cause

The Catalina.out file SEVERE error indicates that tomcat is trying to reload an old session that was present before tomcat was restarted or system was rebooted. At times, this file can become corrupted during a crash and cannot be accessed by tomcat when it is restarting.

Resolution

The following steps can be taken to resolve this issue and regain access to Report Advisor: 

1.     Navigate to $CATALINA_HOME}/work/Catalina/localhost/web/
2.     Locate the file named 'SESSION.ser'
3.     Delete this file. IMPORTANT! Deleting this file will tell tomcat NOT to try and reload the last session. instead tomcat will create a new session.
4.     Restart tomcat service
5.     Try to access Report Advisor again.

At this point you should be able to access Report Advisor again.
