Hi,
I don't know if this is an NFS bug, but seems a lot like it... My
server-host exports a few NTFS filesystems (read-only exports) using
NFSv4. Two client-hosts mount these file-systems.
Client A runs 2.6.31, and client B 2.6.32. Client A works fine. Client
B, while it initially mounts everything ok, and for some time
everything works ok (or so it seems), after a while it starts
returning "Stale NFS file hande" errors for random files and
directories. Client A NEVER returns stale errors, EVEN after a server
reboot.
Has anyone seen something like this before? Is it a known problem?
Who's to blame (probably me... but anyway).
Any additional information you may require I will try to provide.
Thanks in advance.

Some additional details:
On the server
# uname -a
Linux moviesserver 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24
09:00:03 UTC 2010 i686 GNU/Linux
# cat /etc/exports
/mnt *(fsid=0,ro,crossmnt,async,insecure,
all_squash,no_subtree_check)
/mnt/mydvds8 *(fsid=1,ro,async,insecure,all_squash,no_subtree_check)
/mnt/mydvds1-2-7 *(fsid=2,ro,async,insecure,all_squash,no_subtree_check)
/mnt/mydvds3-4 *(fsid=3,ro,async,insecure,all_squash,no_subtree_check)
/mnt/mydvds5-6 *(fsid=4,ro,async,insecure,all_squash,no_subtree_check)
/mnt/mydvds9 *(fsid=5,ro,async,insecure,all_squash,no_subtree_check)
The /mnt/mydvdsXXX directories are mountpoints of NTFS filesystems on
USB drives (if this has any relevance).
On client A:
# uname -a

On Client B:

... same as above ...
On client B, after the problem appears:
# ls /mnt/thepat/*
/mnt/thepat/mydvds1-2-7:
