Hi everyone! Apparently we are experiences issue with the Health Checking system of App Engine. We have disabled the regular health check mechanism as explained in this doc page <https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml#health_checks>. And, in fact, we do not receive any logs of requests pointing to */_ah/health*.
But if we filter by *nginx.health_check* logs we see logs for health check requests to */_ah/vm_health*. First of all, we do not know what this is exactly. Second, we see a long sequence of requests to */_ah/vm_health* that are answered *200* and then suddenly it become *503*. And after some of them, like 15ish requets that answered *503*, the server reboots. What could be the causes of this? Where can I point my eye to search for answers and possibly solutions? Any help is very appreciated. Thank you very much -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
