That looks like a splat every minute or so. I've now had it run for
almost 10 minutes and I've not seen anything except:

2016/02/15 17:26:25 local-0: saving crash 'not executing programs' to crash-local-0-1455553585720015733
2016/02/15 17:29:25 local-0: saving crash 'not executing programs' to crash-local-0-1455553765740119317
2016/02/15 17:32:25 local-0: saving crash 'not executing programs' to crash-local-0-1455553945767974819
2016/02/15 17:35:25 local-0: saving crash 'not executing programs' to crash-local-0-1455554125793957186

And those files are completely empty of useful.
