There is an exclusive ENQUEUE held on to LOGONIDS resource and all other tasks wait for the resource and the system goes into a hung state. Display of command D GRS,C
Release : 16.0
Component : ACF2 for z/OS
The issue is related to the password encryption with AES2 encryption takes a much longer time than regular xdes or aes1 encryption due to the number of iterations of the encryption process.
This is standard for all ESMs.
A password on a new logonid might only be a few seconds but a change to a logonid with password history active might take a much longer time - depending on the number of passwords in the password history - as each history entry must be checked for duplicate password.
