[Zope] Zope Sybase database connection keeps closing

[Abhilasha Chaudhary]

My zope Sybase database connections keep closing for no apparent reason.
When I try to reopen the connections they sometimes give me the 
following error:

*Invalid connection string: *|database: , password: access, server: 
SYBTIGR, transactional: Y, user: access

When I make a copy of the connection object that is giving this error, 
the original connection reopens
automatically.

This behavior seems really bizarre and is causing our Zope website to 
remain unavailable.
