Hi Pat,

epel is disable -- but there were packages installed from epel. I removed everything with
"rpm -e --nodeps `yum list installed | grep epel | awk '{ print $1 }'`"
and now the server seems to be happy again.

At one point yum complaint that rpmdb was altered, got rid with  
"yum history sync"
