[Zope-DB] diconnecting

[Matthew T. Kromer]

Sadly, what a Zope DA thinks of as being "connected" is usually woefully 
incorrect.  In fact, the only thing "connected" means is that the 
database WAS connected, not that it is.

The DA is supposed to perform a reconnect if the database goes down, but 
it only changes the "connected" state if it can't reconnect to the 
remote end.

So instead, what the problem would appear to be is that the DA isn't 
properly closing and reopening the connection when it fails.  What DA 
are you using?
