[Zope] Problem with Z Psycopg

[Jason Leach]

I'm having a problem with Z Psycopg.  From time to time (quite often)
it looses the connection with the database and I get:
   Site Error
   An error was encountered while publishing this resource.
   Error Type: OperationalError
   Error Value: no connection to the server

Then I have to login then close and open the connection.  It then
works for a while before bailing again.

Does anyone know what would be causing this?

Zope Version (Zope 2.7.3-0, python 2.3.4, linux2)
Python Version 2.3.4 (#1, Oct 13 2004, 21:44:19) [GCC 2.95.4 20011002
(Debian prerelease)]
And ZPsycopg is version 1.11

Thanks,
Jason.
