I am using the PHP Toolkit to connect to my Salesforce organisation. Information on the tookit can be found here:
https://developer.salesforce.com/page/PHP_Toolkit
However, I have been getting errors now and then while using my app. The error is written below:
SoapClient::__doRequest() [<a href='soapclient.--dorequest'>soapclient.--dorequest</a>]:
php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in soapclient/SforcePartnerClient.php on line 46
These errors do not occur all the time, they only pop up now and then. The app is still working (most of the time). In my testing, I have never received this message, however, when deployed to the server with multiple client apps that connect to it, this error does get logged a couple of times a day.
Granted, there are hundreds or thousands of actions taken in the app per day. Error messages pop up in the iOS interface that there are connection problems. I am unclear as to whether they are actual internet connection issues (as the app is being used on mobile devices in various public locations) or the above is the source of the connectivity error messages.
Googling the error, I understand that the main reasons for this are normally DNS issues. For other users of the PHP toolkit, is this failure in name resolution inevitable and will occur sometimes when connecting to the Salesforce servers? As this only occurs a few times a day, when compared to the vast number of interactions per day, the impact is minimal.
However, I am a little bit of a perfectionist and trying to figure out if there is any way to eliminate this completely. Is there a problem in my server configuration or is it elsewhere?
