Common Errors and Messages

"User attempted to view a resource which does not exist"

This usually happens after running a single-device discovery. When Open-AudIT finishes auditing a single device, it automatically deletes that discovery entry. If you refresh the page, there's nothing left to load — hence the error.

This is not a real problem. Check whether the device was audited and added to the database. If it was not found, check the discovery logs via Menu → Admin → Database → List Tables → discovery_log.

"MySQL total number of locks exceeded"

This is a MySQL performance issue, not an Open-AudIT bug. It typically appears under heavy load — many simultaneous discoveries or very large datasets.

Solutions:

  • Increase MySQL's innodb_lock_wait_timeout value
  • Reduce discovery_limit to run fewer parallel discovery processes
  • Add more RAM to the server (MySQL benefits enormously from memory)
  • Move the database to an SSD

LDAP Login Not Working

If users are having trouble authenticating via LDAP:

  1. Verify the LDAP server settings under Menu → Admin → LDAP Servers
  2. Confirm the user is a direct member of the relevant LDAP group (not just an inherited member)
  3. Check the Open-AudIT logs for LDAP-specific error messages (increase log_level to 7)
  4. Test LDAP connectivity from the Open-AudIT server using ldapsearch

For detailed LDAP configuration steps, see the How-To Guides section of the wiki.

Apache Will Not Start on Windows

Check that the Apache service account is set to a regular user account, not "Local System". The Local System account has no network access, which means Open-AudIT cannot copy audit scripts to remote Windows devices.

See Installing on Windows for the step-by-step fix.

"No License" Splash Screen After Upgrade

After an upgrade, Open-AudIT may occasionally show the license activation screen again if the license file was not preserved correctly. Click Restore My Licenses to pull your existing license from the database — you should not need to re-activate.

If the Restore option does not work, contact FirstWave support with your original license string.
