Hi,
We are running nfs v 4.1 on centos 7.6.
We are seeing an NFS issue where when files/dirs are deleted from a
client they are occasionally stuck at unlinkat system call(according
to strace its stuck for 100.5 secs every time). Can anyone explain
this behavior?
Running tcp dump shows nfs4err_delay status sent from the server to
the stuck client.
