212	persistent connections not being remapped	Nevins Bartolomeo	somebody	"When using keepalive with least_conn in the upstream module if an upstream is marked down temporarily when it becomes active again the keepalive connections do not get remapped so the server never receives any connections if your connections per second are less then your keepalive connections:

upstream backend_boxes {
	least_conn;
    	server 10.64.157.252;
    	server 10.9.5.195;
    	server 10.214.145.134;
    	server 10.108.77.171;
    	server 10.215.46.107;
    	server 10.210.134.54;
	keepalive 30;
}

10.215.46.107 was marked down due too:

proxy_next_upstream error timeout http_502 invalid_header;

and after it came back up it is no longer receiving requests."	defect	closed	minor		nginx-module	1.2.x	worksforme			Linux hostname 2.6.32-346-ec2 #51-Ubuntu SMP Fri Jul 6 17:41:21 UTC 2012 x86_64 GNU/Linux	"nginx version: nginx/1.2.3
