Greetings,
I also see those opps message in my /var/log/messages... but I'll just pile on here... since this topic is about the new 2.6.18 kernel. Perhaps I'll end up filing a bugzilla report.
On the physical host, it shows an odd process:
[root@new ~]# w
15:08:16 up 1 day, 21:20, 2 users, load average: 0.08, 0.25, 0.25
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 65-100-77-107.bl Sat20 26:13m 2.09s 2.03s tail -f /home/cvs/server-root/mint/CVSROOT/history
root pts/1 scott.coe.montan 15:00 0.00s 0.04s 0.01s w
Further investigation shows:
[root@new ~]# ps auxwww | grep cvs
501 18877 0.0 0.0 1848 560 /vz/root/104/dev/pts/0 S+ Nov05 0:02 tail -f /home/cvs/server-root/mint/CVSROOT/history
Noticed that w shows the process being run on the physical host but ps actually shows it is being run on vps 104.
More info:
[root@new ~]# vzctl enter 104
entered into VE 104
-bash-3.00# w
15:10:15 up 1 day, 21:18, 1 user, load average: 0.00, 0.05, 0.04
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
frank pts/0 wh58-508.st.uni- Sat18 36:30m 2.03s 2.03s tail -f /home/cvs/server-root/mint/CVSROOT/history
So, it appears that w on the physical host is confused and thinks root from host X is running the tail... when in reality, it is a completely different user, sshed in from a completely different host on a VPS rather than the physical host.
Weird, huh?
