Weird nfs issue after TL upgrade
We recently upgraded 2 of our AIX 6.1 servers from TL4 to TL5.
Both servers are on the same p7 780 frame, installed at the same time from the same image. Both servers are mounting the same nfs share after reboot what worked perfectly fine until the upgrade.
Since the patching, one of the two boxes became unable to see files in the share bigger 2GB - the other system doesnt have this problem.
Workaround we currently use is to drop nfs and have it recreated. After the recreation and remount of the filesystems all files are visible / accessible - until we boot, than the bigger 2 gig files become unavailable again.
Has anyone seen a similar behavior and know how to fix it permanently?
Regards

mount.nfs
MOUNT.NFS(8) System Manager's Manual MOUNT.NFS(8)
NAME
mount.nfs, mount.nfs4 - mount a Network File System
SYNOPSIS
mount.nfs remotetarget dir [-rvVwfnsh ] [-o options]
DESCRIPTION
mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality.
mount.nfs is meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone
command with limited functionality.
remotetarget is a server share usually in the form of servername:/path/to/share. dir is the directory on which the file system is to be
mounted.
Under Linux 2.6.32 and later kernel versions, mount.nfs can mount all NFS file system versions. Under earlier Linux kernel versions,
mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2.
OPTIONS
-r Mount file system readonly.
-v Be verbose.
-V Print version.
-w Mount file system read-write.
-f Fake mount. Don't actually call the mount system call.
-n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making
an entry.
-s Tolerate sloppy mount options rather than fail.
-h Print help message.
nfsoptions
Refer to nfs(5) or mount(8) manual pages.
NOTE
For further information please refer nfs(5) and mount(8) manual pages.
FILES
/etc/fstab file system table
/etc/mtab table of mounted file systems
