I don't know if NFSv4 improved the situation at all. So you can do something like this to test it:
flock -x /nfsv4/file -c "sleep 10; echo hello >> /nfsv4/file" & flock -x /nfsv4/file -c "echo world >> /nfsv4/file" #10 sec delay The second command won't execute until the first one releases it's lock. Remove the sleep and loop it repeatedly across for multiple clients, and look for errors in the NFS logs.
