nfs

Essentially, lock manager stops responding (lockd/nfslock), but shows as running as a kernel process. If I bounce portmap and nfslock, it has no effect.

Doesn't show up in the portmapper registered services rpcinfo -p .. doesn't show nlockmgr. it just shows portmapper and status

If I manually remount the drives, it fixes the issue. I'm assuming that the service (lockd) goes stale or hangs when there is no NFS activity? It seems like issuing a mount for NFS volumes "awakens" it and things work once that happens. Please help me nail this down for point me to somewhere to get more information on what might be happening.
