Well, there are three broad problem areas that I'm looking to fix:

- leaking of Oracle connections/sockets. This seems to be fixed by emptying the 
ZODB cache, which feels a lot like a Zope/ZOracleDA/DCOracle2 bug to me.

- inability to reconnect when the server goes away under certain circumstances. 
The ORA-01012: not logged in and ORA-03114: not connected to ORACLE errors. 
IIRC, Matt K said there was code that should re-connect in circumstances such as 
there. It doesn't appear to be currently working...

- Zope hangs due to Oracle servers not responding. Something somewhere should be 
timing out and it ain't currently ;-)

Who else is experiencing any or all of these problems?
