I'm not sure if this is related but I also have noticed occasional RCP 
lock errors like the following in the system logs on the servers:

    Jan 29 11:19:42 stanley kernel: [162386.441677] svc: failed to
    register lockdv1 RPC service (errno 97).
    Jan 29 11:22:39 stanley kernel: [162563.036625] svc: failed to
    register lockdv1 RPC service (errno 97).
