Description of Shift:

run spill time comment
------------------------------------------------------------------------
14681 00:23 Run started with one less proccess on the filter
planes. This causes a net increase in the pre-
formance of filtering as now gateway has a CPU to
itself. See logbook p 114-5 for explaination.

14681 20 DAQDEAD from ktev3. This is thought to be do to
ktev3 filter code now being forced to run on
individual CPUs.

14681 01:45 Run stopped so that recent changes to ktev3 are
undone. Filter planes are still running one
less proccess.

on the couch.
