U3 update crashed - now many duplicate rpms

[Alois Treindl <alois astro ch>]

Yesterday I was using up2date to update a RHEL 3 system to the U3 version.

In the rpm installation phase, the up2date process was hanging, after 
about half of all installs.

When it had been hanging for nearly an hour, I killed the up2date 
process, having to use kill -9 to get rid of it.

Rerunning up2date then failed, it did hang always without any activity.

I decided to reboot the system this morning, successfully, and
did run up2date again.

It reported about 20 more necessary installations, which went without 
problems.

But it seems that du to the killling, not all final cleanup operations 
have run.

I find now many duplicate rpms on my system, e.g.

etc

(using rpm -qa|sort to get a sorted list)

Is there a way to get rid of the duplicates, or do I have to go through 
the listing and use rpm -e for all older versions?

I am also worried that not all post-install scripts have run as they 
should, so that possibly some subsystems are in an incoherent state.
