Hello,

We are using the Zope - Sybase DA (SybaseDAv2) to interface multiple =
application servers to a Sybase 11.9.2 backend server. Both are running =
Redhat 6.2. Periodically, the database connection is being lost on one =
or more of the application servers. When this happens, the DA database =
connection cannot be re-established until zope is restarted. Any =
requests made give the error '<method> is not connected to a database'. =
Access is no problem with the isql client from the same machine. It =
seems to me that the DA is getting into a state where it is blocking db =
requests for some reason. Has anyone else seen this type of behavior? Is =
there a fix or workaround?

Thanks in advance,
Mike Thompson
