[GitHub] [incubator-dubbo] zhangyz-hd commented on issue #3262: "No provider available in XXXX" RpcException after server IO Busy

除了本次因为IO BUSY长达十几分钟造成所有NettyClient状态异常外，日常偶发的IO毛刺，也会造成个别的NettyClient异常，但此时因为还有其他的NettyClient可用，所以服务调用表现正常，只是在统计角度看可能出现服务提供方的调用次数不均衡。比如：
1，偶尔的Full GC的STW；
2，gcore生成dump时几分钟的高IO；
