Hi

I got some but not that much errer log in error.log like : round robin upstream stuck on 1 tries while connecting to upstream, client: xxxx
, server: xxxx, request: "GET xxxx”

I tuned log level to critical, it appears every 10 , 20 or 30 mins, I
am using upstream module for load balancing with about 10000+ established
connection. Does it mean that my frontend servers are overloaded or the backend
servers/VIP response is too slow?

my “frontend server” directives looks like : proxy_connect_timeout 10s; proxy_send_timeout 10s; proxy_read_timeout 10s; proxy_next_upstream timeout;

and my “upstream “ directives looks like: upstream mini.tudou.com { xxxx; backend server xxxx:80 ; backend server xxxxx:80 ; }

Thx Jie
