I set up a freestyle job which has a single "Execute shell" build step, and
is run on a remote node. The shell script starts some jobs in the
background, then waits for one of them to exit, then kills them all with
"killall -9 jobName || echo dead", then at the end it "exit 0" to signal
success. There are no post build steps.
Despite "exit 0", the job fails. It would be useful if the "FATAL: Remote
call on instance-1 failed" message includes the failure reason.
There are some "Also:" stacktraces printed, see below, which don't appear
when the script contains only "exit 0". Do you think these are related to
the failure?
How can I find what's causing this failure?
