[Zope] Problem with Zodb connections pool

Hi all,
I've a system with Zope 2.8.8 that since some weeks is very slow.
The python process keeps busy the CPU (98-99%) and the memory used by
the process is growing up.
Every day a script makes a pack of the ZODB and restarts Zope so the
Data.fs size is stable (about 350MB).

In the event.log I can see many of this warnings:
2009-10-14T11:59:14 WARNING ZODB.DB DB.open() has 8 open connections
with a pool_size of 7

What does it mean?

I can see also some of these messages:
2009-10-14T12:14:16 INFO ZODB.Conflict database conflict error...

According to you, are the two messages related?

Thank you very much
