the configured user limit (128) on the number of inotify instances has been reached
在DotNet核心中读取json文件时出错“已达到inotify实例数量的配置用户限制(128)”
解决方法：

临时：
$ echo 65536 > /proc/sys/fs/inotify/max_user_instances

永久更改：

vi /etc/sysctl.conf #添加如下内容

fs.inotify.max_queued_events = 32768
fs.inotify.max_user_instances = 65536
fs.inotify.max_user_watches = 1048576

sysctl -p #使修改后文件生效
