17B

Explanation
A program running in supervisor state, key 0 issued
the PURGEDQ macro with an incorrect value in the ASID parameter. The
address space for the specified ASID does not exist.

System action
The system abnormally ends the task that issued
the PURGEDQ macro. 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=17B,ACTION=SVCD,END

System programmer response
  Do the following: Ask the operator to set a SLIP trap to obtain an SVC
dump.
In the system trace, look for an SVC 7B entry. The
address in the PSW ADDR column for this SVC entry is the address of
the calling module.
Use the PSW address to identify the module that issued
the PURGEDQ macro. For an installation-provided module, continue diagnosis with the
module.
For an IBM® module, search
problem reporting data bases 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 SVC dump and the logrec data set error record.
