This happened to me when I mounted an NFS share as root, and didn't have 
a no_root_squash option on the share definition.  What does
    ls -ld /data/home/docorbin/foobar 
show?

Also, does your dcorbin account have the same UID on both systems?

It also happens when you have a fail-over cluster, and the secondary 
machine has a slower netork connection than the first.  :)  Ask how long 
it took to track that little thing down!

Thanks and HTH
