I have a problem with umount (fwd)

[Maria Cristina del Solar]

Hi,

When I shutdown the machine, it appears the following message:

Unmounting file systems: umount2: Device or resource busy
umount: /var: device is busy

Unmounting file systems (retry): umount2: Device or resource busy
umount: /var: device is busy

before to run shutdown, I execute:

fuser -vm /var

later I do stop to all the related services

/etc/init.d/httpd stop
/etc/init.d/syslog stop
/etc/init.d/audit stop
/etc/init.d/crond stop
/etc/init.d/atd stop
/etc/init.d/gpm stop
/etc/init.d/nfslock stop
/etc/init.d/xinetd stop
/usr/local/sbin/postfix stop


then run reboot, but the problem persist

Important: I have Red Hat Linux AS 3.0 update 4

Best Regards
Thanks in advanced
