binary-factory MacOS builds seem stuck since Oct 22

I am unable to duplicate this. See the binary factory.

Following your link, I see Build 1185 from 22 Oct "almost complete" and clicking through the Console Output says 'macOS Builder 1' is offline. I've opened a sysadmin ticket.

True, but yesterday the build succeeded.

Am I looking in the wrong place? The top of that page shows the last successful artifact was from build 1184, which was 21 Oct. The top row of the Stage View is from 1185, started 22 Oct but no progress.

Also, on the left, it shows #1186 is (pending—Build #1,185 is already in progress (ETA: N/A))

Fixed. The run from 22 Oct has completed (successfully) and the next run which was started today run seems to be in process.

The message from sysadmin was "Looks like the Jenkins agent process on the builder has fallen over - i've now restarted it. Apologies for that oversight."

Starting to happen again?

The Nov 01 run hasn't finished and next build 1193 (Release_macos) is pending,
same with Nightly_macos which runs at an earlier time.

I've filed a new sysadmin ticket.
