107: ZIPB-EVT-OUTQPARITY
A parity error was detected on the OUTQ of the IPB interface.
Unconditional Tokens
Cause. A parity error occurred in the OUTQ of the IPB interface.
Effect. The error counter is set to zero.
If more than 10 of these errors accumulate in the error counter for the bus, the
operating system shuts down the bus to all the processors and issues the ZIPB-EVT-
BUSDOWN (101) event message. The error counter is cleared if no errors are
detected for 19.2 seconds.
Recovery. Normally, no recovery action is necessary. If the error continues to occur,
see Recovery Action Requiring Vendor Support on page 4-6.

Token Description
ZEMS-TKN-EVENTNUMBER Event number for this message. Value is ZIPB-EVT-
OUTQPARITY (107).
ZIPB-TKN-BUS Is the subject token that specifies the bus. Value is either 0
(X bus) or 1 (Y bus).
ZIPB-TKN-CPU Processor number of the processor reporting the error.
ZIPB-TKN-OUTQPARITY Number of parity errors.
ZIPB-TKN-RPTCPU Processor number of the processor reporting the bus error;
it is the sending processor that encountered the OUTQ
parity error (same as ZIPB-TKN-CPU).
