我遇到一个情况，就是，mongodb 在 mac系统下，在测试的时候经常会报这个错误，并且接下来就会导致mongo数据库崩溃

表现形式是，启动mongodb的时候会有告警

** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000

报错

Listener: accept() returns -1 errno:24 Too many open files2016-12-07T11:14:31.911+0800 E NETWORK  [initandlisten] Out of file descriptors. Waiting one second before trying to accept more connections.

崩溃

解决方法很简单

ulimit -n 10000

即可
