does any one know what this eip msg mean?

I am assuming this eip msg is related to memory:

VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day...

Some process failed to be killed and had
files open on a mounted volume. It
could be an NFS mount which went stale,
or a process which hung waiting for a
kernel function to return.

Getting a PS and mtab listing at that point
in time would help pin down the problem.

System will complete shutdown (self-destruct)
anyway after 5 seconds. It is most likely
you will have active (waiting for resource)
processes when the system shuts down.

If this is a one time occurance I would not
worry. If it happens frequently, then
I would investigate further.
