Hi, I have a quick comment for now, before going deep through your config.

Normally this means that a server is failing to respond to some health checks, either because it crashed or froze, or because it's overloaded. What I see is that your "contimeout" is set to 8 seconds and you have no "timeout queue". In this case, the queue timeout defaults to the contimeout, which is rather short. It means that when all your servers are saturated, a request will go to the queue and if no server releases a connection within 8 seconds, the client will get a 503. At least you should add "timeout queue 80s" to give more chances to your new client requests to get served within the previous requests' timeout. While this is a very high timer it might help troubleshoot your issues. Regards, Willy
