NFS is dynamically loaded. 3. the volume to be mounted is located on the machine that is being rebooted. 4. it is a union mount (this might not be significant). All of the first 3 conditions are necessary to cause the hang. The hanging mount_nfs command cannot be terminated with kill -9 and prevents normal NFS server activity, and perhaps more. -- Adam David
