These problems were also happening for another
non-home mount, but I hear what you're saying.

This is the only cluster we're seeing the problem
on, but then this is the only cluster with a
Sun storage server. All the others are using
CentOS 5.X. Do you think this problem could
be caused by the server? Also, what do you
believe the fundamental cause is?
