What kind of limitation? Instead of raising number of threads on one
zope instance you should just use few Zope instances with smaller number
of threads. AFAIK it's more effective.

So install deadlockdebugger and look at it's output between 8:00-10:00.
It may be safely used on production instances.

Also check if some external resources like LDAP are not restarted/backed
up or sth. like that at this time, or before (eg. there is a backup at
night that causes 'something' wrong for connections from your zope and
your users start working since 8:00 - thats when you see 'hangup').
