Problem accessing home account

Update:

This turned out to be a problem with a login node that had some problems. This machine caused some NFS server processes to hang which was causing a problem with some people's home directories. This should be cleared up now (12:30 PM 06/19/2012].

A problem popped up this morning in which some home account directories can not be accessed. We are investigating the issue and will have further updates as they become available.
