Symptoms

In an environment where clients mount filesystems from the ZFS Storage Appliance utilizing NFSv4 protocol,  it was reported that the requests for file access were hanging, and additionally commands such as ls and df were also unresponsive.
The same filesystems mounted via NFS v3 or SMB/CIFS are responsive.
