[Zope] Zope stops responding...

[Chris McDonough]

Was there anything noteworthy in the Z2.log right before it stopped 
responding?

This behavior would be consistent with that of a ZODB database 
connection leaking every once in  a while, until seven of them are 
leaked after which Zope sorta sits there stubbornly with its arms 
crossed not doing anything at all.

You could prove or disprove this by making it happen again while "big M" 
logging was turned on... if you analyze the big M log with 
requestprofiler and you see "hangs" in the output that aren't caused by 
a restart, these are likely thread leaks.
