Summary

You have set IWSVA to update every 15 minutes. Once or twice a day you receive a notification that there is a “generic failure on source network,” but after 15 minutes another successful update occurs.

The Active Update module searches server.ini as the update source on the update server. The server.ini file records the update information.

When a new pattern or component is available, the old server.ini file is deleted before the new package and server.ini is uploaded to the server. Between this deletion and uploading of the server.ini file, there is a time interval of five (5) minutes. If your scheduled update coincides with this interval, an HTTP 404 error occurs because the update source, server.ini, is not found. You then receive the notification from IWSVA.

To avoid the update failure notification, increase the time interval between retries:

  1. Open /usr/iwss/lib/aucfg.ini.
  2. Look for the [Downloader] section and add the line “retry_delay”.

    This "retry_delay" is the time in milliseconds before another connection retries the update. The default value is 0, and setting it longer than five (5) minutes will avoid the issue.

    It should appear like this:

    [Downloader]
    Retry=3
    retry_delay=360000
  3. Save and close the file.

You can also set the update frequency to be longer than 15 minutes. This will decrease the possibility that the issue will occur.
