SendBufferToWorker fail. May be the send buffer are overflow. See http://wiki.workerman.net/Error2 for detail
提示这个按照流程去strace -p 查找其中一个端口发现

报错的意思是gateway收到消息转发给businessWorker处理，但是向businessWorker发送数据的发送缓冲区已经满了，无法发送。

如果客户端发送请求的速度大于businessWorker的处理速度，并且这种情况持续一段时间后就会报这个错。比如客户端每秒发送10000个请求给服务端，gateway收到请求后给businessWorker处理，businessWorker每秒只能处理9000个请求，那么请求就会积压在缓冲区，最终缓冲区满了就报这个错了。

出现这个问题这个一般是businessWorker处理不过来了导致的，看看Events.php里是否有处理很慢的业务，businessWorker进程数是否足够(进程数一般是cpu的3倍)。如果业务都ok，那么说明此服务器配置+你的业务代码无法支持这么大的请求量，可以通过分布式多服务器部署水平扩展服务器来解决。

请问这个缓冲区可以扩大吗客户端每10秒会给我发送心跳我会记录一些东西可能是这个地方堵死了吗？

进程数是CPU的3倍？我看gateway进程数建议与cpu核数相同 bussinessWorker进程数量和这个不一样吗？

bussinessWorker 不一样，要比cpu多一些

start_gateway.php中 $gateway->sendToWorkerBufferSize来设置这个缓冲区大小，默认10M
