我们的一个用户环境有 Apache/2.4.34 (Win32) OpenSSL/1.0.2o 配置。Apache 进程每天退出一次并自动重新启动。重新启动后一切正常。他们已应用补丁 (SSL)。这可能是重新启动的原因吗？Apache/2.4.34 (Win32) OpenSSL/1.0.2o 配置是否存在兼容性问题
Apache 进程在不到一天的时间内将内存增加到 1.5G，大约在午夜 12 点，它会自动释放内存，然后有时会立即重新启动，有时会正常运行几个小时，然后重新启动并退出代码为 3221225477 。
我的疑问是如何检查内存增加的原因以及如何找到重新启动的原因？
通常错误日志不会报告除 AH00428 之外的任何错误：父进程：子进程 xxxxx 以状态 3221225477 退出——正在重新启动。
访问日志似乎没问题。重启时我们在 access.log 中没有看到任何日志消息。一两天来，我们在午夜左右在 error.log 中观察到以下错误，但 apache 在这些错误之后没有立即重启。

他们没有在午夜安排任何事，他们有一个每天 4 点运行的 cron 作业，这个 cron 作业每天还会重新启动 apache。抱歉发了这么长的帖子。任何帮助都将不胜感激。
答案1
由于 Apache 默认堆栈大小较小，此问题经常发生在 Windows 中。并且它通常发生在使用分配大量堆栈的 php 代码时。
为了解决这个问题，在 apache 配置文件 httpd.conf 的末尾添加以下内容
<IfModule mpm_winnt_module>
ThreadStackSize 8888888
</IfModule>
