Symptom: Item in restart times error: Critical: Exception loading sessions from persistent storage. The problem is caused by the session persistence mechanism of Tomcat, which is intended to maintain the previous session after rebooting Tomcat, but after Tomcat is not properly shut down, Tomcat attempts to resume the session with read failure. Throws an error without affecting the system's use.
Solution:
If you need to avoid this problem, disable Tomcat's persistence feature, specifically to modify the Server.xml file under Conf. Add a code to the context of the project <manager classname= "Org.apache.catalina.session.PersistentManager" saveonrestart= "false"/ > Reboot Tomcat will never report this error again.
