When I add to my contab jstop before actual job submission I get message which says: "NOTE: some crontab entries have been modified to grid submissions. You may want to examine the result with 'crontab -e'."

When I look to my crontab I see jstop will be submitted to grid.

So my question, does jstop command and grid managing commands in general, really have to be ran on grid? Are they that resource heavy commands?
