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.
I was talking about the limitation u say here: "Also there are some rules about pool-size. I don't remember exactly but seems to me that it is too small, but in general I suppose it has nothing to do with your problem..." I will search more about use of ZEO. Thanks.
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').
I think is something on LDAP, Deadlockdebugger is running already and tomorrow i will have the answer. Thank u all...
