umount /var: Device busy

[Rainer Dorsch <rdorsch@web.de>]

Hello,

when shutting down my etch system, I get a

umount /var: Device busy
  Failed

During the next reboot the /var partition is checked, but there is never an 
inconsistency found, looks like the partition is at least synced during 
shutdown.

The only uncommon thing at this system, I remember:
I upgraded the system twice from woody to sarge and recently from sarge to 
etch, though I am not sure if the problem came with the upgrade.

Does anybody have an idea how I could find out why the device is busy?

Thanks,
Rainer
