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
