We have observed some modify user IM tasks are failing if the user attribute (passworddata) becomes too large.
Release : 14.5
Component : CA Identity Manager
This issue occurs if the passworddata attribute becomes large.
Workaround: After clearing the passworddata attribute, we can resubmit the tasks and they complete successfully without issues.
The issue is resolved after adding the property DISABLE_JDK_SERIAL_FILTER=true in the standalone.sh file for the application server.
