I googled for this issue, and found this[1]:
A filehandle becomes stale whenever the file or directory referenced by
the handle is removed by another host, while your client still holds an
active reference to the object. A typical example occurs when the
current directory of a process, running on your client, is removed on
the server (either by a process running on the server or on another
client).
So this can occur if the directory is modified on the NFS server, but
the directories modification time is not updated.
How do I fix this problem?
* The best solution is to remount directory from the NFS client
* Or try to mount NFS directory with the noac option. However I don't
recommend using noac option because of performance issue and Checking
files on NFS filesystem referenced by file descriptors (i.e. the
fcntl and ioctl families of functions) may lead to inconsistent
result due to the lack of consistency check in kernel even if noac is
used.
