Hello,

I'm not using a relayd so I can't tell exactly. The relayctl(8) says:

    host disable [name | id]
             Disable a host.  Treat it as though it were always down.

    host enable [name | id]
             Enable the host.  Start checking its health again.

so the whole issue feels like a kind of bug. See further below for comments on
change itself. Note I'm not very familiar with relayctl code.

			^^^^
			I'm not sure if it is right place for TAILQ_FOREACH()
			over all tables here. The thing is the loop does call
			disable_host() recursively. So each level of
			recursion is going to walk over the same set of
			all tables relayd keeps.

			also lines exceed 80 characters.
