Vulnerability network scans stuck in queued

Ernest_za

All vulnerability network scans are stuck in a Queued state and do not start, although Discovery scans are running successfully. Network scans remain permanently queued with no progress.

Has anyone encountered this before or have suggestions on where to begin troubleshooting?

Steps already taken:

• Confirmed that all scan nodes are online, healthy, and fully updated.
• Verified scan restriction schedules, and all affected scans fall within allowed time windows.
• Rebooted all scan nodes multiple times.

Any guidance or ideas would be greatly appreciated.

Thanks.

Hi @Ernest_za

Thank you for raising the issue regarding vulnerability network scans remaining in a Queued state while discovery scans continue to run successfully. We understand how disruptive this can be and appreciate your patience as we work through it together.

Here are some recommended troubleshooting steps:

1. Check Scan Group Limits:
   Ensure that your scan group settings do not restrict the number of simultaneous scans. Increasing this limit (if safe to do so) may help resolve the queue.
2. Verify Scan Node Assignment:
   Confirm that the correct scan nodes are assigned to your scan groups and that they are communicating properly with the management console.
3. Review Scan Node Health:
   Even if scan nodes appear healthy, double-check their connectivity and recent activity in your management portal.
4. Resource Availability:
   Make sure all scan nodes have sufficient disk space and memory available.
5. Software Updates:
   Confirm that all scan nodes are running the latest supported software version.
6. Backend or Cloud Load:
   In some cases, high backend or cloud load can cause scans to remain queued. If all settings appear correct and the issue persists, please reach out to support for further investigation.

If you have already tried these steps and the issue continues, please reach our WithSecure Support team and provide the following information:

• The version of your scan node software
• Any relevant scan log excerpts (excluding sensitive information)
• Confirmation of your scan group and node settings

This will help our support team and provide more targeted assistance.
