In this particular case, they are releasing the volumes every five minutes. Depending upon when the VLDB info was obtained there may not be a full set of file servers listed that are up to date from the perspective of the client. The Windows client has a 10 minute interval for resetting the status of an offline volume to online. I can certainly see how the specific circumstances here can (a) result in an incomplete set of readonly instances to start with and a failure when none are left in an online state. Jeffrey Altman
