This sounds like the same problem I used to have and helped debug. There
have been a number of changes in CVS that address this. The problem is on
the server-side, and relates to how permissions are rechecked when a
handle has expired from the dentry cache. XFS CVS from May 22 2002 or
later does not exhibit this problem. A patch a month or so ago also
addressed a problem with umasks across NFS effectively being ignored.
I strongly recommend trying a CVS kernel out on the NFS server and seeing
if the problem goes away for you. I am currently running XFS CVS from
around that time in May plus some of the "critical" patches that I have
seen TAKEs for and haven't seen the problem since that time and have had
no stability problems on my 3 file servers serving up over 2TB of data to
about 1200 clients.
Regards,
Chris
