RPM error/ corrupt database???

["A.J. Werkman" <werkman digifarma nl>]

While installing tftp-server and tftp client through the command "rpm -Uvh 
tftp*.rpm" rpm hung after it had reached the 100% count on installing the 
first rpm.

After this every rpm command (like rpm -qa) hangs forever (well at least 15 
minutes). The only thing to stop the rpm-process is a "kill -9". <contrl>-c 
on the controling console isn't doing much then.

In the "/var/lib/rpm"-dir I found a few files "__db.*" with the current 
timestamp. So I thought I'd remove them. After doing so the "rpm -qa" 
command is functioning again.
But as soon as I do a "rpm --rebuilddb" rpm stops with the following message:
[root werk root]# rpm --rebuilddb
error: db4 error(16) from dbenv->remove: Device or resource busy
[root werk root]#

Then the "__db" files appear again, making rpm non responsive again. On 
deleting these I can do an "rpm -qa" again. Here is the listing of my 
"/var/lib/rpm"

Is my rpm-database that much corrupt now that I should consider a complete 
reinstallation. That would make me feel bad, because I would be like a 
Win-user (If something fails reinstall the system).

Is there a more linux-like solution to this problem?

Thanks in advance, Koos.

BTW I am running rh9 not-upgraded ( I intended to, but this problem stop me 
to) on a dual xeon system here.
