Sun GridEngine: resetting queue status on node

I occasionally run into problems with space during a run on my cluster, which causes the job to fail and the node to be marked as unavailable:

Before you do anything else, free up space and consider moving your scratch dir to a different/separate disk.

Since I keep forgetting how to reset it, here it is -- as a SGE admin do:
 /usr/bin/qmod -c four.q@tantalum

me@beryllium changed state of "four.q@tantalum" (no error)

And now everything is good:
