040

Explanation
The system abended a task during nucleus initialization
program (NIP) processing.
The right-most four bytes of the program
status word (PSW) have the following format: x0cccwww
 where: x
Irrelevant information.
ccc
A hexadecimal abend code indicating the reason for the failure.
www
The wait state code.

System action
The system issues message IEA303W. The system
enters a non-restartable wait state.

Operator response
Record the wait state PSW and report the problem
to the system programmer. If the system programmer requests it, obtain
a stand-alone dump.

System programmer response
See the system programmer response
for the abend code displayed in message IEA303W.
The abend SVC
entry in the system's SVC table contains the address of a trap routine
in NIP, and not the address of the abend SVC.  The registers (0 through
15) at the time of the abend SVC request are found in the area pointed
to by field NVTDIAGA (mapped by macro IHANVT).
If the problem
persists, search problem reporting databases for a fix for the problem.
If no fix exists, contact the IBM® Support
Center. Providing the contents of the wait state PSW.
