Observation 10804096 has this setup.
We see that in the long MSDECOM output of the
ampl/ampl residual matrix - XX (Promille)
a high value for the 6X and 6Y combinations.
By not choosing 6X and 6Y it becomes normal,
but by also
choosing 6X and 6Y AND NOT choosing 9X and 9Y AND DX and DY it becomes normal.
This has to do with the consistency of the 6-combinations.
(see also the appended msdecom.log file)
Hans van Someren Greve will have a look why or what is the reason of these values. |

We did some test and the effect has disappeared.
It has been for more than 10 days in the system but could not be seen
in the latest test this morning.
So for now we will trace this problem. |

We have seen that after the reboot of the DZBSystem on 22-08-2008 that
this problem was there, after the reboot on 02-09-2008 is was disappeared.
This was also the date we did our tests for this problem and also after the reboot. |

The effect is now active again. (10-09-2008)
The only thing what has changed is a TMS reboot has been done,
NOT a DZBSystem reboot. So controllers has been stopped and started.
So far we know there are no new controllerversions of Read-/CtrlDZB. |

H v. Someren Greve has also looked for this problem, he remarks
that Albert Bos should have a look in the DZBSystem for this problem. |

CorBoard 5 from unit 3 changed with CorBoard 5 unit 2. Due to the 4096 channels problem. If there are now problems it should appear in the combinations 2=D= and 9=D= |
