Hi folks,
AFAICS the RFCs about NFS don't define NFSERR_EAGAIN, so I
wonder why is it in nfs.h?
enum nfs_stat {
NFS_OK = 0, /* v2 v3 v4 */
:
NFSERR_NXIO = 6, /* v2 v3 v4 */
NFSERR_EAGAIN = 11, /* v2 v3 */
NFSERR_ACCES = 13, /* v2 v3 v4 */
NFSERR_EXIST = 17, /* v2 v3 v4 */
:
Reason for asking is: I'm running a NFS server on Linux.
NFS on a Solaris 10 client gets stuck several times a week.
/var/adm/messages on this client says
:

:
(nfs-home and nfs-data are host name aliases for the same Linux
server.)
It seems to follow this pattern: first there is an EAGAIN, and some time
later NFS on the client stops working with these "still trying" messages.
Other clients are not affected, AFAICS.
Any helpful comment would be highly appreciated.
