我的也有
You can disable this behavior by adding,

proxy_next_upstream error;

to your nginx.conf. Default value for this setting is "error,  
timeout", so nginx tries to connect to the next mongrel when the  
current one returns an error or timeouts in your case. I noticed this  
when I saw multiple copies of same comments on our site.
