Explanation

text is one of the following:
  • INVALID
  • LOOP IN

The stand-alone dump program found a control block in the specified address space in error or unavailable.

In the message text:
yyy
The control block.
asid
The address space identifier.
address
The address of the control block.
INVALID
One of the following exists:
  • The control block did not pass the validity check.
  • The pointer to the control block was zero.
  • The control block could not be obtained from the stand-alone dump work file or the system paging devices because:
    • An I/O error occurred on the device; in this case, message AMD033I also appears.
    • I/O failed to initiate.
    • The operator replied I to message AMDO12D for a device on which intervention was required.
    • The virtual address is not defined on external storage.
    • An incorrect or unavailable control block was required to page in the control block; in this case, message AMD018I precedes this message.
