NOTE: If you are not familiar with linux, don't try this, get the thalia ops team involved. These are very rough notes, more a reminder to developers who have already done these things. If you have not, please involve ops rather than trying to do it yourself.

Is alfresco running? Go to http://thalia-dev.mit.edu:8130/alfresco/faces/jsp/dashboards/container.jsp  

 Try:
/etc/init.d/web stop
ps \-aux \| grep tomcat
There should only be 2 \-\- one for tomcat, one for the tomcat within alfresco. If there are more than this, kill the tomcats that are NOT alfresco.
kill \-9 \[id for thalia tomcat server\]
ps \-aux \| grep tomcat again to make sure there is only the alfresco process running
then /etc/init.d/web start to start the thalia web server
