Exception loading sessions from persistent storage The solution to this problem

It is often reported when a project is restarted:

Critical: Exception loading sessions from persistent storage problem.

The reason for this is that the Tomcat session persistence mechanism, the Tomcat feature itself, is meant to hold the previous session after rebooting Tomcat, but after Tomcat is shut down, the read fails when Tomcat attempts to resume the session. Throws an error, but does not affect the system's use.

If you need to avoid this problem, disable Tomcat's persistence feature, specifically to modify the Server.xml file under Conf. Add a line of code to the context of the project:

<manager classname= "Org.apache.catalina.session.PersistentManager" saveonrestart= "false"/>

Restarting Tomcat will never report this error again.
