To verify you have the same packages installed, can you create an Audit Job that compares the "RPMS" object of each server?
that message is coming back from our run of up2date against our repository of RPMS that you're point at - to me that points to something on the box, or possibly a missing RPM in the repository
I have ran an audit job that compares the RPMs on both servers and that come back with no differences.
However when i compare the up2date.dryrun log on both servers, i see additional 32-bit packages installed on the server where the analysis in completing which are not being picked up in the RPMs audit.
When i run "rpm -qi ", their is no way of differentiating whether its a 32-bit package or a 64-bit package at the OS level.
the x86_64 vs i386 might be the issue. to see the arch of the packages use:
rpm -qa --queryformat %-%-%-%"\n"
