the per-process limit

has been reached, or the per-process limit on the number of open file descriptors has been reached.
部署一个asp.net core程序，用着用着占用线程数越来越多，看报错日志发现这么一行：the configured user limit (128) on the number of inotify instances has been reached。

解决：

For Linux:
Check current value of max_user_instances:
$ cat /proc/sys/fs/inotify/max_user_instances
increase that value:
$ echo 256 > /proc/sys/fs/inotify/max_user_instances
In order to make that change permanent add a line to /etc/sysctl.conf:
fs.inotify.max_user_instances = 256

平台中直接配置禁用（如果配置文件修改了，需要手动重启）
