Issue/Introduction

This can occur in a clustered environment where you submit create identity task and sporadically the task will fail some of the clustered nodes.

Cause

This issue was be caused by a discrepancy in the time between the servers.  This can also be caused by a custom PXpolicy or JavaScript.

 

Environment

Clustered environmentIDM 12.6.8Websphere

Resolution

Check all clustered nodes.  Is the date\time synced? Are they exactly the same and synchronized through NTP? 

https://en.wikipedia.org/wiki/Network_Time_Protocol

The nodes not matching the date\time exactly caused the issue.  Even a slight deviation can cause sporadic values depending on the date\time needed being used in the task.  This could cause the time functions to report as null as we were seeing here but also not always happen depending on the criteria of the task. A PXpolicy or Javascript could return different values depending on the nodes because of time not synced. 

Drill into a failing task and look at event. Review which event failed and depending on the failed review the change values of the event.  Do you have a custom PXpolicy or Javascript date\time causing the issue? 

Restart the problematic nodes.  Monitor the nodes that were effected restarted for any of the failed create user tasks. If another factor caused a node sync issue restarting would also help resolve the issue.  This would also resolve any PXpolicy issues that could return NULL values due to a clock sync issue.
