EC2 Haproxy stops taking requests

[Umair Khan]

Hi,

I am using haproxy with Apache to keep alive an EC2 server. Sometimes
haproxy stops taking new requests during this period we can't open our
website, If I reload haproxy service it starts working normally. I have
disabled iptables and increased open file limit but no luck. Below is my
configuration.
Please guide me to what I did wrong.
