根据上述错误跟踪，I/O 反应器已关闭。当您尝试使用已关闭的 I/O 反应器发送消息时，您将收到类似于上述错误跟踪的错误。当 I/O 反应器关闭时，如果不重新启动 MI 服务器，则无法恢复。关闭 I/O 反应器是一个关键问题，这通常不会由于配置而发生，而是由于某些环境因素造成的。

这可能是由于系统中打开的文件数量不足而发生的。因此检查您是否已按照本文档中给出的步骤来优化操作系统级别的性能？

此外，您可以使用以下命令检查当前 WSO2 进程的允许文件限制。

请替换为 wso2 进程 ID。

cat /proc/{PID}/limits

您可以使用以下命令检查用于运行 WSO2 EI 进程的用户的软文件和硬文件限制。

ulimit -Hn
ulimit -Sn
