Thank you for your help Alvaro - we really appreciate it.
The error in fact stopped this morning - we took downtime and ran a vacuum
across all of our tables, and saw increased auto vacuum activity as well.
It looks like it bumped up the oldest multitxid to something other than 1 now:

Your right we looked back in our old logs and we do see the messages there
as well. Still what I'm not getting is since we restarted the database
after SAN FC re-cable effort auto-vacuum is running on all the threads
continuous. I have never seen auto-vacuum using all the threads 24*7 on

Thanks. We started seeing this error right after a SAN FC re-cable effort - so
yes, that would make sense.
We’ll do a little more digging to see if the could have gotten removed.
If that’s an older file that we have in our filesystem backups, is it safe to
restore from there?
