将环境从python2.7更改为python3.6后apache中的分段错误

Question

我正在尝试在debian服务器上将python环境从2.7.15+升级到3.6.9。在部署最新的python 3代码并安装需求之后，我注意到apache开始在错误日志中给出以下错误：

[Fri Dec 06 02:34:52.076909 2019] [core:notice] [pid 24549:tid 139967202941888] AH00051: child pid 24553 exit signal Segmentation fault (11), possible coredump in /etc/apache2
[Fri Dec 06 02:34:53.079944 2019] [core:notice] [pid 24549:tid 139967202941888] AH00051: child pid 24552 exit signal Segmentation fault (11), possible coredump in /etc/apache2

基于this link，我尝试分析coredump，得到的结果如下：

(gdb) bt full

我搞不懂这个。有谁能帮我找出哪里不对吗
