Yes I understand Alan is right on, and that vmcp protect's itself with a limited buffer. But when I did the same command from the console instead of using the vmcp command on the guest, it brought the entire server down. VMCP limits the amount of output through buffers, how does VM limit output from commands from the console? I should have phrased my question that way.

The "vmcp q term" does not generate so much output that it does not fit in the standard vmcp buffer, so you should be fairly safe issueing that command. An other option is to issue from an other authorized VM user (for instance MAINT) the command "FOR <linux_guest_id> CMD QUERY TERMINAL" For what it is worth, in my days as an operator (a long long time ago), we intercepted the "D T" command, sometimes issued by MVS operators to "Display Time". Only on VM it was a "Dump Terminal", so we were less amused when that got issued under OPERATOR ......
