Issue/Introduction

Identity Manager encountered an error.
Contact your admin and provide the information displayed below.

Error Code 500

In the System Diagnostics dashboard, the Clocks section shows a warning state, indicating one or more nodes are not synchronized with the cluster.

Environment

• VMware Identity Manager 3.3.7
• Multi-node Cluster deployments

Cause

This issue occurs when the systemd-timesyncd service interferes with time synchronization or when the clock drift between nodes exceeds the allowable threshold for cluster operations.

Resolution

Complete the following steps on all Identity Manager nodes simultaneously to ensure synchronization:

1. Log into the Identity Manager node as root via SSH or Console.
2. Stop and disable the systemd-timesyncd service to prevent conflicts:

   systemctl stop systemd-timesyncd && systemctl disable systemd-timesyncd

3. Start the ntpd service:

   systemctl start ntpd

4. Verify the time is now consistent across all nodes by running:

   date

5. If the time is still out of sync, manually force a sync with your NTP server:

   systemctl stop ntpd
   ntpdate -u <NTP_IP_OR_FQDN>

6. Restart the service:

   systemctl start ntpd
