已经达到了求解实例数量的用户限制（128）

Question

我正在使用ubuntu 22.04运行.net 6项目。当我同时运行2或3个项目时，我会收到此错误：

System.IO.IOException: The configured user limit (128) on the number of inotify instances has been reached, or the per-process limit on the number of open file descriptors has been reached.

长期我运行.net在ubuntu上，我以前曾经遇到过，但不记得我解决了这个问题。完整的堆栈跟踪：

Unhandled exception. System.IO.IOException: The configured user limit (128) on the number of inotify instances has been reached, or the per-process limit on the number of open file descriptors has been reached.

更新1：

它是ulimit -a的结果：

更新2： 到目前为止，我已经使用了几个环绕量。但是，最后，这个问题解决了我的问题：

echo fs.inotify.max_user_instances=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

这是来自这个问题。
