Explanation
An error occurred during processing of the hardware
instrumentation services (HIS). Register 15 contains a hexadecimal
reason code describing the error. The first halfword of each reason
code (xxxx) is set by the system and contains internal
information. The following reason codes only list the external errors.
Any unlisted reason codes are internal and should be reported to the IBM® Support Center.
Reason code
Explanation
xxxx8001
System storage is exhausted or not available.   System Action: HIS
does not perform the requested operation. The HIS address space is
not initialized if system storage cannot be obtained.  
Programmer
Response: Free up system storage and resubmit the HIS job.

xxxx8003
It takes too long to write the sampling data.System Action: The
data collection activities are stopped. HIS waits for the sample data
to be written out. However, a preset wait time expires and not all
data have been written.
Programmer Response:  Assign
a sufficiently high dispatch priority to the HIS task, so that the
sampling data can be written to the output in a timely manner. If
the problem still exists, search problem reporting databases for a
fix for the problem. If no fix exists, contact the IBM Support Center.

xxxx8005
The CALLRTM macro was issued against HIS main task.  System
Action: The HIS main task is being abnormally ended by calling
the recovery termination manager (RTM).  This is a generic abend reason
code.  The specific reason for the CALLRTM action can be found in
the accompanying error messages, or SVC dumps (for unexpected errors). 
Programmer
Response: Analyze the accompanying error messages for the cause.
Resubmit the HIS job after the error has been corrected.

System action
The system abnormally ends the HIS address space.

System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting databases for a fix for the problem. If no
fix exists, contact the IBM Support
Center.
