Thanks Trevor for pointing out that there is an option for such thing is slurm.conf. Although I previously greped for *wc* and found nothing, the correct name is TrackWCKey which is set to "yes" by default. After setting that to "no", the error disappeared.
About the comments on Rocks and the Slurm roll... in my experiences, rocks 7 is very good and the unofficial slurm roll provided by Werner is also very good. It is worth to give them a try. Although I had some experiences with manual slurm installation on an ubuntu cluster some years ago, the automatic installation of the roll was very nice indeed! All the commands and configurations can be extracted from the roll. So there is no dark point about that. Limited issues about slurm, e.g. installation, are directly related to Werner. Most of the other question are related to the slurm itself. For example accounting and other things.
