Patrick, as I understand it, this problem is patched in a new version of
the KLAEXPB4 file, which Unison should send you.

> The following was sent to Unison Technical Support on 5/15/98. (I
> haven't heard back yet; but now the problem is more serious because we
> upgraded our largest production system (a 995/500) on Saturday and it
> has the same problem):
>
> We are running KLA Express A.02.02 on an HP3000 928. When we upgraded
> from MPE/iX 5.0 (C.50.00) to 5.5 Release 4 (C.55.00) we encountered a
> problem with Express and have had to disable it.
>
> The problem is that EXPRESS is changing the LIMIT of the circular
> queues
> when we haven't told it to. We normally have them tuned as follows (as
> they appear on the main Express screen):

> CS=152,220,1,2000
> DS=202,238,2000,2000
> ES=240,253,2000,2000

> ------QUANTUM-------
> QUEUE BASE LIMIT MIN MAX ACTUAL BOOST TIMESLICE

> EQ 240 253 2000 2000 2000 DECAY 200
