[LUDOC-174] sgpdd-survey normal output produces errors (says failure when all is well)

Mon, 17 Oct 2016 14:53:24 +0000

See the output below.

We could just fix up the script so it says something other than failed
in this case.

It could say something like
"out of memory for this config" or just pass the unexpected log line
along to the end user so they can parse it.
