Comments on Errors

Note: a summary of the NHK messages encountered this month, listed in increasing frequency of occurrence, may be found at http://msslje.mssl.ucl.ac.uk/lists/nhklis_2006-08.txt

Corrupted EEPROM Data (S-Swift-0422)

[2006-08-08 06:47:09.1] This appears to be a recurrence of the already documented NCR 158.

DPU Unexpected ACK/NAK

[2006-08-23 01:54:04.54] This appears to a premature DPU timeout that should not have occurred. This has been logged as SOAR S-Swift-0423.

Illegal APID

[2006-08-08 05:22:23.01 and 2006-08-08 06:33:13.01] This is a recurrence of the error documented in last month's report. It was fixed shortly afterwards [at 07:45].
