Subject Re: Requesting node X to shutdown to ensure failure?
Date Sun, 30 Sep 2018 19:50:24 GMT
Hi Till,

These files are indeed the same log file. I just extracted one line from
the original log and placed the line at the beginning. At 9:50 pm, the CC
initiates a task cluster and all NCs were executing. Node 2 sent the
taskcomplete message, and somehow the CC decides to shut down the node 2.
That's my understanding.

Best,
Taewoo
