can't check-in for RedHat up2date

[Albert DE WINT <adwint pandora be>]

Hi,

Early this week, I (re)installed Redhat9.
I haven't been able to check-in for RedHat's service: 'up2date'.

The 'up2date' applet indicates a check-in failure a couple of minutes
after start-up.

I checked my account on the RedHat's site and followed the guidelines:

- I update my system's profile at the RH site - OK
- I checked on my system's status: it's active and entitlements are OK
- It shows my system does not need any updates right now. 
  (I think it DOES need updates!)

- I checked if the rhnsd daemon is running - OK

Then I tried to rebuild the RPM database, (it might be corrupt)

- First, I checked if any rpm processes had to be killed, using command.

	$ ps -axwww | grep rhn_check (also checked other rmp processes)

No PID's to be killed showed up.

Then I removed the RPM lock files (/var/lib/rpm/__db*):

	$ rm -rf /var/lib/rpm/__db* (removal confirmed)

Finally I did (as root):

	rpm --rebuilddb
	error: db4 error(16) from dbenv->remove: Device or System Source 	busy

I don't understand, maybe I missed something?

Thanks to anyone for helping me out.

Albert
