Mac Mini M1上MacOSX Sleep系统调用异常问题求助

在Mac Mini M1上运行服务时，白天多次出现几秒到20分钟的莫名随机延迟，该服务在Linux上运行完全正常。疑似macOS的Sleep系统调用存在严重问题。这台机器未运行其他程序，仅安装了少量开发工具，未连接屏幕和键盘。

最小复现案例 #

#include <iostream>
#include <thread>
#include <chrono>

int main()
{
    for (;;)
    {
        std::this_thread::sleep_for(std::chrono::seconds(10));
        const auto now = std::chrono::system_clock::now();
        std::cout << "Wall clock: " << now << std::endl;
    }
}

异常延迟示例 #

本该休眠10秒却休眠了15分钟的情况多次出现，日志如下：

Wall clock: 2024-07-02 05:34:08.577015
Wall clock: 2024-07-02 05:34:18.705682
Wall clock: 2024-07-02 05:34:28.853954
Wall clock: 2024-07-02 05:50:42.539091
Wall clock: 2024-07-02 05:50:52.582264

launchd配置文件 #

通过launchd运行测试程序的plist配置：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>localhost.sleep_test</string>
        <key>Program</key>
        <string>/usr/local/bin/sleep_test.sh</string>
        <key>RunAtLoad</key>
        <true/>
        <key>StandardOutPath</key>
        <string>/Users/user/sleep_test-output.txt</string>
        <key>StandardErrorPath</key>
        <string>/Users/user/sleep_test-errors.txt</string>
    </dict>
</plist>

启动命令 #

% launchctl load localhost.sleep_test.plist
% launchctl start localhost.sleep_test
