Processor Halt Codes Manual

Cause
An IPU failed to dispatch processes while there were processes ready for it to dispatch. The
number in the least significant four bits (that is, n where the halt code is %002400 + n) is the
number of the IPU that stopped dispatching.
Effect
The logical processor halts.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump of the halted
processor and contact your service provider or the Global NonStop Solution Center (GNSC),
as directed by your local operating procedures.
%002420
Cause
The Process Scheduler was started too early during process initialization.
Effect
The logical processor halts.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump of the halted
processor and contact your service provider or the Global NonStop Solution Center (GNSC),
as directed by your local operating procedures.
%002422
Cause
The Process Scheduler has lost integrity.
Effect
The logical processor halts.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump of the halted
processor and contact your service provider or the Global NonStop Solution Center (GNSC),
as directed by your local operating procedures.
%002423
Cause
The Process Scheduler has fatally failed to rebalance disk processes.
Effect
The logical processor halts.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump of the halted
processor and contact your service provider or the Global NonStop Solution Center (GNSC),
as directed by your local operating procedures.
%003000
Cause
Not enough physical memory exists to load the processor.
Effect
The processor-load operation fails; the processor remains halted.
