Summary

0000165: Timeslip in delay control

Description

On a regular basis we receive error messages of a timeslip in the delay steering
The first impression is a communication error. It is possible that one of the network ports of the Nortel switch is causing this problem. (remark by Teun Grit) We have only seen it for 8 band configurations.

Additional Information

20090909:
To trace the error message "Timeslip detected in Delay control" from the
CtrlDZB.log the archive stream(from wop29 to dop158) had been switched off
yesterday afternoon. But the error message still appeared once at
UT17:54:17,08/09,2009.

20090910:
Now the archive stream has been switched on again.
