deployed in qr2hi. Works as expected: doesn't blow up-

but it brought 2 nodes when needed only 1: https://workbench.qr2hi.arvadosapi.com/pipeline_instances/qr2hi-d1hrv-78qs9xv7ycr2j6s

new bug?

new bug?

Node Manager can be in a state where it gets an updated job queue before it gets an updated node list. If the timing is just right, it can see that there's a new job in the queue, but sees the node as still busy with the previous job in the pipeline (that just finished). In that case, it will boot a new node, even though a complete snapshot of the all the system states would show it's not necessary.

This has been true forever, so it's not a "new" bug, no.
