Yes, but to answer your question:

At that point, the update was done simply by a 'yum -y install couchdb'.

There used to be safeguards to prevent the vm.args change and other issues, but 
I isolated all of them (once I knew what was going on) and the safeguards are 
now all in place.

Many thanks.
