Is it an AFM cache? We see this sort of behaviour occasionally where the cache 
has an "old" view of the directory. Doing an ls, it evidently goes back to home 
but by then you already have weird stuff. The next ls is usually fine.

I am sure this is a known behavior and I am going to feel very foolish in a few 

We often see this behavior on a GPFS filesystem.
I log into a client.

[jhearns@pn715 test]$ ls -la ../
ls: cannot access ../..: Permission denied

This behavior changes after a certain number of minutes, and the .. directory 
looks normal.

For information this filesystem has nfsv4 file locking semantics and ACL 
semantics set to all
