05A

Explanation
Supervisor control detected an error in a request
to free a service request block (SRB) or to free a suspended SRB (SSRB).
Register 15 contains a hexadecimal reason code to be used when searching
problem reporting data bases or when reporting the problem to the IBM® Support Center.

System action
The system abnormally ends the program that tried
to free the SRB or SSRB. The system may write a logrec data set error
record.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=05A,ACTION=SVCD,END

System programmer response
Do the following: Use the address in register 14 at the time of error
to identify the module that tried to free an SRB or an SSRB.
Search problem reporting data bases for a fix for the problem.
If no fix exists, and no dump was written with the abend, ask the
operator to set a SLIP trap to obtain an SVC dump. Search problem
reporting databases for a fix for the problem. If no fix exists, contact
the component group associated with this module at the IBM Support Center. Provide the dump used, the
reason code of the failure, and, if available, the logrec data set
error record.
