Last update: September 1, 2026

This article explains how to address recurring Segment Not Found workflow failures in Adobe Experience Manager (AEM) Forms Author environments, which are temporarily resolved by restarting the instance.

Description description

Environment

Adobe Experience Manager (AEM) Forms Author environment

Issue/Symptoms

  • Workflows fail with a Segment Not Found error when submitting forms.
  • The issue recurs periodically, such as once a month.
  • All workflow submissions are affected during the incident.
  • High CPU usage and slow responsiveness are observed on the Author instance.
  • Restarting the Author instance temporarily resolves the issue.
  • No recent changes to workflows or system configuration are associated with the onset of this issue.

Cause

The root cause may be related to resource exhaustion, memory leaks, or storage/database issues, but the exact cause is not specified.

Resolution resolution

To fix the Segment Not Found workflow failure, follow these steps:

  1. Restart the AEM Author instance:

    1. As an environment administrator, perform a controlled restart of your AEM Author server.
    2. Ensure that all users are notified of the planned downtime, if applicable.

  2. Monitor the server after restart:

    1. Confirm that the Author instance starts successfully and is responsive.
    2. Attempt to resubmit previously failed workflows to verify that the issue is resolved.

  3. Check CPU usage and system load on the Author instance after restart to ensure normal operation.

  4. Evaluate the number of workflows typically queued and processed, especially during peak usage periods.

  5. Consider adjusting workflow scheduling or balancing workflow load to reduce resource contention.

  6. If the issue recurs, investigate potential underlying causes such as resource exhaustion, memory leaks, or storage/database issues related to the Segment Not Found error. Consider engaging your IT team or AEM administrator for further analysis and long-term solutions.

After completing the steps above, confirm that workflows can be submitted and processed successfully without encountering the Segment Not Found error.
