What did you do?

gomote create aix-ppc64
# host type "host-aix-ppc64-osuosl" is not elastic; 0 of 1 machines connected, 0 busy

What did you expect to see?

A gomote created in a reasonable amount of time

What did you see instead?

I reset the command after 15 minutes, and did it again. It's still waiting after 17 more minutes. I'd expect it to be able to free up the gomote for me earlier.

I think this specific problem is primarily caused by the aix-ppc64 builder being offline right now. Filed #39031 for that.
