Hi, I'm using nginx as the proxy application deployed in the cloud foundry space which will route the requests to the upstream servers which are behind the Elastic Load Balancer. I noticed that after 3-4 hours, the proxy application in the cloud foundry space is going down and it's logging 499 response code in the access logs. If we restart the cf app , then everything works fine for sometimeby praveen - Nginx Mailing List - English
