Hi Jan, The best solution to bypass this issue is to cause a refresh of the access_token before you fork the process. Insert the following code before the wile loop:
$oauth2info = $user->GetOAuth2Info<https://code.google.com/p/google-api-adwords-php/source/browse/src/Google/Api/Ads/Common/Lib/AdsUser.php#376> (); $oauth2info = $user->GetOAuth2Handler<https://code.google.com/p/google-api-adwords-php/source/browse/src/Google/Api/Ads/Common/Lib/AdsUser.php#392> ()->*GetOrRefreshAccessToken<https://code.google.com/p/google-api-adwords-php/source/browse/src/Google/Api/Ads/Common/Util/OAuth2Handler.php#102> ($oauth2info)*; $user->SetOAuth2Info<https://code.google.com/p/google-api-adwords-php/source/browse/src/Google/Api/Ads/Common/Lib/AdsUser.php#384> ($oauth2info); However, the danger of using this code with pcntl_fork is that, if any process runs over 1 hour and makes an additional API request, then it could result in another rate limit exceeded errors. The issue being, once you pcntl_fork, all values are copied. To resolve this issue, please consider storing the oauth2info in a shared data store. Regards, - Paul, AdWords API Team.
