Suddenly my app started to get 500 error with no reasonable reason, from logs just logMessage: "This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application." logMessage: "While handling this request, the process that handled this request was found to be using too much memory and was terminated. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may have a memory leak in your application."
I edited the php code of the page and it was this line: list($username,$domain)=split('@',$email); my apps runtime is php55 Why is this all of a sudden (started 3.7.2017) ? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
