It appears that your
Tomcat is configured to use persistent sessions and that an attempt to reload one is crashing the system. Now, I have not used persisent sessions, but if this was my problem I would comment out the section of your server.xml that decares persistent sessions to be in use. In my server.xml this is a section that looks like:
<Manager className="org.apache.catalina.session.PersistentManager"
debug="0"
saveOnRestart="true"
maxActiveSessions="-1"
minIdleSwap="-1"
maxIdleSwap="-1"
maxIdleBackup="-1">
<Store className="org.apache.catalina.session.FileStore"/>
</Manager>
-----------
Hopefully, if it does not see that configuration, it won't try to reload the session.
