Hi!
I have a problem with my instances of Zope 2.8.4: recently they started
to run slowly. Restarting doesn't help much.
After observing Zope threads with DeadlockDebugger we found that very
often threads are stuck while trying to access to ZEO cache file.
We have ZEO server and 2 ZEO clients.
so 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 se
g more) to check this next time happen?
Use DeadlockDebugger and if this doesn't help try:
