To check if Crowd is up, in web browser go to the appropriate URL as defined above. 
You should see Crowd log-in page.  If not then ssh in to xxx-crowd.sagebase.org as ec2-user, using the standard key for 'platform' owned ec2 instances, PlatformKeyPairEast

At the unix prompt:

      ps -efwww | grep java

Should show one java process, if not
      cd /usr/local/atlassian-crowd-2.2.7/

     ./start_crowd.sh

Now verify that the log-in page appears in your web browser.

If crowd is running and you feel the need to 'bounce' the server, make sure to stop crowd before running "start_crowd.sh".  To do this, run

    ./stop_crowd.sh

from /usr/local/atlasssian-crowd-2.2.7/.  Use the aforementioned "ps -ef..." command to make sure no Crowd java process is running.  If necessary, 'kill' lingering instances before running "start_crowd.sh".  It's important not to have multiple instances of the java process runnning.sudo reboot

The machine should restart keeping the existing elastic ip.
