 * We are running into an intermittent issue getting a 503 error that is fixed simply
   by clearing the W3 Total Cache plugin cache.
 * Unfortunately, we don’t know when it will occur and it prevents our shopping 
   cart from functioning until the cache is cleared.
 * Do you have any idea why this would occur and how to prevent the 503 error from
   occurring? We are using the latest version of the plugin 0.9.7.

 * I am sorry to hear about this issue however, 503 error usually indicates that
   the server is running our of resources (memory/cpu) . I would suggest going through
   your wordpress installation and disable any unused plugins/themes also, you may
   want to double check the settings on your w3tc and ensure that you are using 
   page cache / browser cache. Also, I would suggest on setting the minify on manual
   mode and make sure that the theme is properly cached.
