That was what I did, and it worked grate, but it presents a drawback.
The users are enable to use scp also. I could bypass this, telling to
invert the scp order ... from the node (accessible through a Qrsh) to
the master instead of the usual way (from the master to nodes). But it
is a little tricky also, cause, what happen if the node are full? the
Qrsh will never give a interactive shell.
How you use to implement this in professionals clusters?

Anyway, about the original subjet, if some want to do a "qrsh
/bin/bash" still put all the queue in E state ... all.
How can I debug it, in order to try to find an explanation, or avoid
that error? Althougt the users are few and trusteable, they could

Thanks in advance,
