Perhaps I'm wrong but I suspect that a Zope I'm running is dying

What are my options for monitoring and debugging what zope's threads
are doing?
Is there a simple tool to just get a simple readout of how many
threads are busy?
One simple option is the ZMI Control_Panel Debug screen. Go to /
Control_Panel/DebugInfo/manage_main on your instance and scroll to the
bottom. It shows current connections to the Zope server from the
outside, and how long the connection has been around. You will always
at least see one entry, which is the request to fetch that debug
screen. If you have connections beyond a few seconds of age they may
be stuck.
