Error description
When nfs4 client makes a blocking lock request and if the lock is unavailable the nfs server would allocate a filock struct to sleep on that lock. Since the nfs client will keep retrying the request, the total pool of filock on the system could eventually be exhausted if the lock never becomes available.
Local fix
Problem summary
System resources eventually get exhausted and the system becomes unusable
Problem conclusion
Add in a check to prevent unnecessary flock structs from being created
Temporary fix
