Thanks for the suggestion. That does not seem to be the problem, unfortunately. So I'm still looking for a way to deal with this problem. Again, I'm thinking about acquiring/buying software that will tell me more about what is going on, though I wish in the short term I had a better idea, because I support students who are unable to register for classes because of this. Thanks.

By that time, the tomcat looks "hang". hope it helps.
