Question

我有两个服务器运行一个非常简单的Phoenix框架API，每周左右，其中一个服务器出现此错误并抛出502.

15:35:08.260 [error] 'File operation error: emfile. Target: /usr/lib/erlang/lib/stdlib-3.2/ebin/erl_posix_msg.beam. Function: get_file. Process: code_server.'

15:35:08.323 [error] 'File operation error: emfile. Target: erl_posix_msg.beam. Function: get_file. Process: code_server.'

如果我重新启动凤凰服务器，繁荣，一切都会重新开始工作。显然，这不是一个可扩展的解决方案，但我正在努力诊断正在发生的事情。

任何帮助都会很好。

阅读OTP erl_posix_msg模块，您会发现它只是“打开的文件太多”的代码。

Elixir - Phoenix - 功能：erl_posix_msg.message / 1未定义
