[Zope] zope unresponsive

I know that there is a switch between zeo and zope and probably a firewall too, but how do I prove this is the problem. This is on production server in a military installation. I have major problems getting any kind of trouble shooting support. First we don't get access, and second no kind of debugging is allowed. You couldn't imagine the paperwork and the three months it took for me to get deadlockdebugger installed. Thanks, Paul
