IEA059E ASID SHORTAGE HAS BEEN DETECTED

Explanation
The number of ASIDs available for allocation to
new address spaces has dropped below 5% of the value specified in
IEASYSxx with the MAXUSER specification.

System action
The first time MVS™ issues message IEA059E for the current IPL, MVS takes a system dump to aid in
diagnosing the situation. System Completion code AC7 with reason code
001B0000 is issued to permit MVS to
take the system dump.

Operator response
None.

System programmer response
Determine if the shortage is due to
too many address spaces being started, MAXUSER being specified too
low, or ASIDs becoming non-reusable for cross-memory integrity reasons.
