[gpfsug-discuss] Issue with X forwarding

Hi All,
We've got a new-ish 4.1.1.0 Advanced cluster and we've run into a strange
problem: users who have their home directory on the GPFS filesystem cannot
do X11 forwarding. They get the following error:
"/usr/bin/xauth: error in locking authority file /home/user/.Xauthority"
The file ~/.Xauthority is there and also a new one ~/.Xauthority-c.
Similarly, "xauth -b" also fails:
Attempting to break locks on authority file /home/user/.Xauthority
xauth: error in locking authority file /home/user/.Xauthority
This behavior happens regardless of the client involved, and happens across
multiple OS/kernel versions, and if GPFS is mounted natively or via NFS
export. For any given host, if the user's home directory is moved to
another NFS-exported location, X forwarding works correctly.
Has anyone seen this before, or have any idea as to where it's coming from?
Thanks,
Vanessa
