Hi,

Plz check the NFSv4 diagnostic storepool 'Alloc' counters which may be close to or exceeding their 'Max' values resulting in exhaustion. If this is the case, it is possible that client misbehavior may be overconsuming NFSv4 storepool objects.

Please see this KB: {covers lot of useful info)

Also, few threads discussing same issue, worth taking a look.

To put it another way, NFSv4 Storepool is a set of resources on the cluster to store a pool of ops on the network layer (often called nblade) while waiting for service from the data layer (dblade) or other resources. If that pool gets filled, it hits a software defined bottleneck and won't allow any more operations from NFS clients.
