Question：cache manager process always exited and new start？
辛苦确认下是不是版本不兼容导致的？谢谢。

upsync version: v2.1.3

[xujpxm]

#193 参考配置建议后，使用include 命令，并在upstream中去除fake server，解决此问题。

[xujpxm]

添加backup server时，依然会有core dumped的报错，配置示例如下：
upstream test {
upsync 127.0.0.1:8500/v1/catalog/service/test upsync_timeout=6m upsync_interval=500ms upsync_type=consul_services strong_dependency=off;
upsync_dump_path /usr/local/openresty/nginx/conf/servers/servers_test.conf;
include /usr/local/nginx/conf/servers/servers_test.conf;
server 127.0.0.1:8080 bakcup;
}
