5/7 at ~1pm one of the blackboard front end servers (app2) started reporting very slow http response. I was not able to determine what was causing this but restarted tomcat and failed all users over to the other server. After restarting App2, App1 started exhibiting the same behavior.
This points to a user process causing the problem. I spoke with Bob
and he had run some large gradebook operations, but nothing else unusual
