Accesses during shift: Now way!

Overview of shift:

Inherited BEAM_832 run 14345.
Ocassional DAQDEAD_SEC of a few seconds. One process on ktev1
is taking 10% more time than the others. The monitor plane
CPU seems a little high so I increased slightly the B01 and B02
monitor pre-scales in dest/BEAM_832.
