A user sees a stale handle in "df" and can't access files and directories. When root issues a "df" or accesses a file or directory on the NFS file system, it gets a correct result. Thereafter a normal user also can access files and directories on the NFS file system. After a short time the NFS handle becomes stale again. /var/log/messages contains the lines: Feb 21 23:33:50 gsr108 kernel: RPC: Can't bind to reserved port (13). Feb 21 23:33:50 gsr108 kernel: RPC: can't bind to reserved port. after a user tries to access a file on the NFS file system. The NFS server runs kernel version 2.4.23 SMP. Client NFS 2.4.23 works. The filesystem is mounted with the following options in /etc/fstab: rw,bg,hard,intr,rsize=8192,wsize=8192 We are stuck and can't upgrade to 2.6.x with this bug.
