huh my understanding based on the documentation for satellite is it
should be fine as long as you only have one instance of taskomatic
running at a time. There is even instructions on how to configure the
clients to be aware of both servers for transparent failover.

It wasn’t smart enough to “reconnect”. I didn’t give it much effort to debug. However that was before the use of SCAN listeners in our environment. I bet leveraging the SCAN LISTENER layer spacewalk would work just fine as a whole.
