can not connect to tcp://xxx Operation now in progress

sxmwhl 更新于2020-08-11

请教一下，这种错误一般怎么处理？
原来在一台服务器上部署没有出现过这种问题，把businessworker部署到局域网上后，偶尔会出现以下错误退出。
是因为Gateway太忙了吗？
谢谢！

报错的时候看下各个服务器的负载是不是高了。有可能是负载高了导致。
另外每台服务器都要装event扩展，并按照手册 http://doc.workerman.net/appendices/kernel-optimization.html 优化linux内核。一般普通内核配置不优化无法承载高并发。

sxmwhl 2019-03-13

都安装有扩展，Gateway的主机安装的libevent, business主机装的event，内核也优化过。
但是优化内核时这一条好像有问题
sysctl: cannot stat /proc/sys/net/ipv4/tcp_tw_recycle: No such file or directory
不知道影响不影响。
另外在开business主机上开status -d 才出现这样的错误，不开就不会出。看错提示里有

12 /var/www/server/vendor/workerman/workerman/Worker.php(1535): Workerman\Worker::monitorWorkersForLinux()

13 /var/www/server/vendor/workerman/workerman/Worker.php(509): Workerman\Worker::monitorWorkers()

估计跟状态实时查看有关系。
Gateway主机是有外网的，businessworker主机没有外网的，我是通过Gateway主机，ssh到business主机上开的status -d
其实，这个错误也影响不大，只是想提供一些线索，供大家参考。

我也遇到这种情况，不知道怎么解决。
也装了扩展，内核也优化了，还是时不时的报这个错误，也没有规律
