Another scan is actively running — either in another browser tab, by another administrator, or from a previous session. Only one scan can run at a time. Wait for the current scan to finish, or check with other administrators. The message shows "last activity X ago" so you can gauge whether the scan is actively processing.
Frequently Asked Questions
Scan Troubleshooting
The scan says "A scan is currently in progress." What does that mean?
I started a scan and navigated away. Did I break anything?
No. If you navigate away during a scan, partial results are preserved. When you return to the scan page, you'll see one of two messages:
- "A scan is currently running" — The scan is still processing in the background. Wait for it to finish.
- "Previous scan appears interrupted" — The scan stopped. You can click Resume Scan to continue from where it left off, or Start Fresh Scan to begin a new full scan.
Your existing inventory data remains intact until a scan successfully completes.
The scan seems stuck. What should I do?
If the scan page shows "A scan is currently in progress" but the "last activity" time is more than 2 minutes ago, the system will automatically detect the scan as interrupted. Refresh the page — you should see Resume Scan and Start Fresh Scan buttons. Click Resume Scan to continue from the last completed phase, or Start Fresh Scan if you prefer to start over.
Why does my browser warn about "repeating an action" when I refresh?
This can happen if you refresh the scan progress page. The browser is asking whether it should re-submit the original form, which sounds alarming but is safe. If a scan is already running (in this or another tab), the system will not start a second one — it will show a message that a scan is in progress and disable the button. You can safely click Cancel in the browser dialog to dismiss the warning, or click Continue — either way, the running scan is not affected.
Will running a scan affect my website visitors?
No. Scanning runs in the background and does not change any content visible to visitors. The scanner reads content to build the inventory — it never modifies pages, files, or media. Visitors can browse the site normally during a scan.
Why do large sites take longer to scan?
The scanner processes managed files, filesystem files, content fields, media entities, and menu links across the entire site. Sites with more assets, content, and complex structures naturally take longer to scan.
Typical scan times:
- ~700 assets — about 40 seconds
- ~7,000 assets — about 5 minutes
- ~20,000 assets — about 20 minutes
Actual times may vary depending on hosting environment, site complexity, and server performance.
If a long scan is interrupted, use Resume Scan to continue from where it left off rather than restarting.
Why did my Digital Asset Scan fail?
I ran a Digital Asset Inventory scan and it did not complete. What happened?
In some cases, the scan may not complete if your site has some other issues or server errors.
What should I do if the scan fails?
Please contact your Site Administrator. They can:
- Confirm whether the module is having issues or not
- Adjust settings if needed
- Ensure your scan runs successfully
You do not need to disable anything yourself.
Will this affect ADA compliance or archive features?
No. This issue does not affect:
- Archived documents
- The Archive Registry
- ADA Title II compliance classification
It only affects the completion of the scan process.
