Hello everyone,

I had to kill yum while it's on the cleanup stage (somehow it stalled
so i killed it).

Should I be worried about anything in this situation? If so, how do I
go about fixing it?
    

I had to do that on one of our servers the other day after a 4.2 ->
4.3 Yum update. I was a little worried but after reboot the system
seemed fine.

Eep. Actually, checking more closely, I appear to have ended up in the
same state as Dave in the "futex.. How to remove lots of duplicate
packages" thread...

http://lists.centos.org/pipermail/centos/2006-March/thread.html#21387

I have a bunch of duplicate packages I'm going to have to sort through
manually and remove the older versions...

rpm -qa --qf "%{NAME}.%{arch}\n" | sort | uniq -d
apr.i386
audit.i386
autofs.i386
  
<<snip>>

ypbind.i386
yum.noarch

Crap. :)

Will.
  
Indeed. "Crap" and its alias.  I had a similar experience in updating 4.1 -->  4.2 and wound up reinstalling and restoring data in my /home directory.   :-(
