[Sorry, wrong subject.]

Dear NFS folks,


We experience the following behavior with the Linux series 4.4 and 4.9.

When the exported directory on the server gets full to 100 % some NFS
clients are unable to access the server anymore, but others can.

The error is, that the server says the client ID has expired. The
server, on which the client runs on, needs to be restarted. Then it
works again.

Can you think of an error path causing such a failure? What would be the
right way to deal with this error?


Kind regards,

Paul
