file descriptor xx left open - problem with LVM on ProLiant ML 350

Hello,
i'm getting the mentioned error in SuSE Linux Enterprise Server 10 SP1, ProLiant ML 350 G4p,
using LVM.
If i type in a xterm (under KDE) e.g. vgscan, vgdisplay, pvscan i get
the message: "file descriptor xx left open", with a one or two digit
number for xx.
Afterwards i see the desired infromations. The LV's are accessible,
reading and writing is possible. When i leave X and start a tty with
STRG+ALT+F2, and then type e.g. vgscan, vgdisplay, i don't get these
mesages !
Following questions:
1. What does these messages mean ? Are they severe ? I searched
already on the net, and found a lot of people experiencing the same
problem, but no one has a solution/explanation.
2. Why do i get these messages in a xterm, but not in a tty. In both
should run the same bash, or ?
3. How can i get more informations about these file descriptors ? E.g.
which process is attached, or which file is it in real ?
Thanks in advance for any help.
Bernd
