The lockd: cannot monitor messages are due to the kernel being unable
to communicate with the rpc.statd process. That usually indicates
that the rpc.statd is not running, possibly due to it crashing.
NFS is a stateless protocol. But file locks are inherently stateful.
To maintain file locks some auxilary programs are used such as the
Check that the rpc.statd is running.
ps -e | grep rpc.statd

# service nfs-common restart
Problems with NFS locking has been a problem forever.
