get_backup_peers方法异常

aduchuan

你好：

我在openResty中使用了upstream-fair这个插件，在upstream中配置

upstream web-server {
    server localhost:8080;
    server localhost:8989;
    server localhost:8090;
    fair;
}

然后使用Healthcheck功能时报错：

failed to get primary servers in upstream: web-server, client: 127.0.0.1, server: localhost, request: "GET /monitor/status_json HTTP/1.1", host: "localhost"

2017/09/04 19:04:26 [error] 3875#0: *10 lua entry thread aborted: runtime error: string length overflow

stack traceback:

coroutine 0:

[C]: in function 'get_backup_peers'

把fair去掉就正常了。
