Hi,

My coaster services are registering 1.2k CPUs at a time.  Yet my jobs
does not seem to get sent to some workers:

Progress:  Selecting site:2762  Submitted:580  Finished
successfully:424 Failed but can retry:138
Progress:  Selecting site:2762  Submitted:580  Finished
successfully:424 Failed but can retry:138

It maybe the case that my workers only has outbound connections and no inbound?

Which coaster-service log entries should I look out for to know if (1)
a job is received and (2) a job is dispatched to a worker (3) blockID
the job was sent to?

Does <Block-ID>: pull refer to a worker receiving a job?
