[comp.os.vms] Crashing monitor

STAM@HROEUR51.BITNET (AC Stam EUR/ERC) (07/08/88)

Monitor has some fine features as was discussed
some months ago, but recently I found another
curiosity about monitor. Now I wonder if what I
saw was
        a) a feature,
        b) site specific or
        c) something else.

The command used was of the format:

$ MONITOR SYSTEM[,...],PROCESSES/TOPCPU/VIEWING_TIME=x

where x is 1,2,3 or 4.

After 4 or 6 screens of statistics *IT* occurs:

%MONITOR-E-UNEXPERR, unexpected error
-SYSTEM-F-FLTDIV_F, arithmetic fault, floating divide by zero at
PC=0000C435, PSL=030000C4

(The PC and PSL sometimes vary)

I have not seen any warning in the documentation about
the conjunction of the qualifiers and parameters used.
