supervisor对tcp连接数有限制

jumbo

我有一个python写的tcp服务进程，在shell下直接启动的时候，可以稳定的接受3000个链接（更多连接没测试），但是挂到supervisor下的时候，只能接受 1000个左右的连接就连不进去了，提示是连接超时。在阿里云和百度云上测试都是一样的结果，系统是ubuntu16.04，我看了supervisor的所有配置项，没找到跟tcp连接有关联的配置，不知大家有没遇到过这个问题，有经验的麻烦帮忙指点一下，不胜感激。

都没有人解决过这样的问题吗？

minfds

The minimum number of file descriptors that must be available before supervisord will start successfully. A call to setrlimit will be made to attempt to raise the soft and hard limits of the supervisord process to satisfy minfds. The hard limit may only be raised if supervisord is run as root. supervisord uses file descriptors liberally, and will enter a failure mode when one cannot be obtained from the OS, so it’s useful to be able to specify a minimum value to ensure it doesn’t run out of them during execution. These limits will be inherited by the managed subprocesses. This option is particularly useful on Solaris, which has a low per-process fd limit by default.

Default: 1024

Required: No.

Introduced: 3.0
