What does this message mean?

Whenever I shutdown or reboot the gateway, Secureplatform NGx R65 with
HFA_02 and hf_249, I see the following messages:

[Expert@dca-bank]# Stopping sshd:[ OK ]

What does this message means:

umount2: Invalid argument
umount: none: not found
umount: /dev/pts: not mounted


I noticed that I see this warning/message on ALL of the NGx R65 gateways
on different hardware: Dell Servers 2950-III, Dell Optiplex Desktop, IBM
x3650 Servers. I am not sure what it means and this is something I should
be concerned with.

/dev/pts is for psuedo terminals and you can safely ignore those errors.
