Answer 1

Tomcat is attempting to save all the session stored objects(which are serializable) as a file called sessions.ser when tomcat shuts down, so that it can bring that session back during startup.

During start it will attempt to read sessions.ser file to restore session. Your problem seems to a permission issue. Try granting read/write privileges to folder /home/grc/grcapp/tomcat/work/Catalina/localhost/grc

using chmod
