我的 apache error.log 有很多段错误：
[core:notice] [pid 16753] AH00052: child pid 4861 exit signal Segmentation fault (11)
并且每隔 10 小时左右就会检测到一些错误：

什么可能导致我的错误？
答案1
看起来故障发生在 ioncube 中。话虽如此，您的网络服务器上加载了大量不同的模块，这并非稳定性的秘诀。您还在同一个实例上运行 2 个解码器。然后出于某种原因，您还混合使用了 cpanel（这使您的问题偏离了主题）。
如果您确实需要所有这些模块和两个编码器，那么您应该首先将应用程序拆分到单独的实例中。
