"hivemq" service fails during restart on RedHat Enterprise Linux 8
Problem

Steps to Diagnose
In RedHat Enterprise Linux 8, all security and authentication-related messages and errors are recorded in the "/var/log/secure" file. To troubleshoot this issue:
Access the /var/log/secure file:
sudo cat /var/log/secure
Review recent user management activity:
Look for any entries related to user additions (
useradd
) or deletions (userdel
).
Solution
Check if these virtual machines (VMs) were imaged based on user IDs set up by your IT department. Update your IT policies accordingly to prevent this issue in the future.
