I found a bug in nfs-version=3 (nw65sp1) - the clients are sun solaris
2.8 workstations and the exported directory is in independent-mode.
First, it seemed to be normal at the nfs-client side, the usual
os-commands like ls, df, mkdir & rmdir, chmod worked fine.
I got the problems with failed commands in an application
After mounted with nfs-version=2 from client side the apps worked fine.

I see no errors on xnfs-trace screen, but <xnfs nfs info> shows an
increased counter on nfs-requests-failed.

Any ideas for deeper analysis ?
