Re: Can't shutdown processes

["Jeffrey Cobb" <cdoc2000 mediaone net>]

Well, that didn't seem to work.

It attempts to load the KDE login the drops back to console and attempts to
shutdown certain processes:

INIT: switching to runlevel: 3
INIT: sending processes the TERM signal
stopping httpd: --failed
shutting down SMB services: --failed
shutting down NMB services: --failed
Starting automount: no mountpoints defined --ok
Starting pcmcia -- ok
Starting wine --failed

login:

I've no clue why it's doing this.  I just login as root and clean out the
/tmp directory, restart xfs and reboot.

KDE will start now, I just notice when I shutdown that there's all these
processes that won't stop.

Any idea how I can clean this up??
