Hi,

We are facing below nfs stale error on every saturday morning,

nfs: [ID 236337 kern.info] NOTICE: [NFS4][Server: andd006][Mntpt: /net/andd006/vobs]NFS op OP_OPEN go
t error NFS4ERR_EXPIRED causing recovery action NR_CLIENTID.
nfs: [ID 581112 kern.info] NOTICE: [NFS4][Server: andd006][Mntpt: /net/andd006/vobs]NFS Starting reco
very for mount /net/andd006/vobs (mi 0x6002c128000 mi_recovflags [0x1]) on server andd006, rnode_pt1 ./tools.vbs/c/cdft/4/28

it works after we remounts the filesystem in nfs client or reboot the client,

solaris version 10
Release 05/08
kernel Generic_127127-11
we changed the nfs client version to 3, then also no use at all.
pls help me to find the root cause for this issue

It looks NFS daemon issues.

Try to change the version of server which is hosting NFS mount point.

Still no resolution, re-install the server with new release 10/09.

Run NFS on version 4,
