報(bào)錯(cuò)的意思是gateway收到消息轉(zhuǎn)發(fā)給businessWorker處理，但是向businessWorker發(fā)送數(shù)據(jù)的發(fā)送緩沖區(qū)已經(jīng)滿了，無(wú)法發(fā)送。

如果客戶端發(fā)送請(qǐng)求的速度大于businessWorker的處理速度，并且這種情況持續(xù)一段時(shí)間后就會(huì)報(bào)這個(gè)錯(cuò)。比如客戶端每秒發(fā)送10000個(gè)請(qǐng)求給服務(wù)端，gateway收到請(qǐng)求后給businessWorker處理，businessWorker每秒只能處理9000個(gè)請(qǐng)求，那么請(qǐng)求就會(huì)積壓在緩沖區(qū)，最終緩沖區(qū)滿了就報(bào)這個(gè)錯(cuò)了。

出現(xiàn)這個(gè)問(wèn)題這個(gè)一般是businessWorker處理不過(guò)來(lái)了導(dǎo)致的，看看Events.php里是否有處理很慢的業(yè)務(wù)，businessWorker進(jìn)程數(shù)是否足夠(進(jìn)程數(shù)一般是cpu的3倍)。如果業(yè)務(wù)都o(jì)k，那么說(shuō)明此服務(wù)器配置+你的業(yè)務(wù)代碼無(wú)法支持這么大的請(qǐng)求量，可以通過(guò)分布式多服務(wù)器部署水平擴(kuò)展服務(wù)器來(lái)解決。

請(qǐng)問(wèn)這個(gè)緩沖區(qū)可以擴(kuò)大嗎客戶端每10秒會(huì)給我發(fā)送心跳我會(huì)記錄一些東西可能是這個(gè)地方堵死了嗎？
xc6163355 2017-09-15

進(jìn)程數(shù)是CPU的3倍？我看gateway進(jìn)程數(shù)建議與cpu核數(shù)相同 bussinessWorker進(jìn)程數(shù)量和這個(gè)不一樣嗎？
walkor 2017-09-15

bussinessWorker 不一樣，要比cpu多一些
walkor 2017-09-15

start_gateway.php中 $gateway->sendToWorkerBufferSize來(lái)設(shè)置這個(gè)緩沖區(qū)大小，默認(rèn)10M
