我有一个apache服务器，该服务器为我的移动应用程序提供一些REST API。我的error_log中出现分段错误，并注意到我所有的Apache进程都逐渐建立到最大内存，直到其中一个崩溃。我生成了一个核心转储，但是我不确定如何从这里继续查找问题。
以下是段错误的回溯信息：

对我来说幸运的是，这并没有真正影响我的应用程序的基本功能，因此它仍然可以正常运行，只是它会不时断开用户连接（同样不会影响用户体验）
我尚未配置MPM设置，例如KeepAliveTimeout或maxconnections或其他任何设置。
我当时想通过更改一些MPM config id可以缓解此问题，但我不想让情况变得更糟。
感谢任何指导或帮助。我正在使用Apache 2.4.33
