JESX006A error message in MIMQUERY after zOS 2.3 upgrade

Products

• MIM Data Sharing (MII)

Issue/Introduction

We had just upgraded one of our test LPARs to zOS 2.3. After the IPL, we are receiving the following message on MIMQUERY address space startup:

*JESX006A - @VERSION IS NOT HJE77B0  - CONTACT SOFTWARE SERVICES ASAP 

Is there any recompile missing ? It does not seems to be a CA MIM message.

Environment

Release : 12.5

Component : MII

Resolution

This is not  MIM related.
A usermod customization for another product is responsible for issuing that message, it was also received in another task's address space.
