There are no log entries from the state manager (or anything else from NFS). When I reboot the system with the Debian provided 2.6.32 kernel the problem goes away. Does anyone have an idea why this would be occurring? I have included the kernel config file from the client. One thing you could do to capture more information about the problem is to run a network trace on a client that is in this state. The procedures and error codes on the wire might be illuminating. -- Chuck Lever chuck[dot]lever[at]oracle[dot]com
