python-3.x - 如何处理python中发生的分段错误

问题描述

我已经编写了一段代码来检查系统中是否存在数据库中的新条目，如果找到新条目，它将获取数据并且客户端将尝试将其发送到服务器......但是如果数据在每次执行 threading.timer 循环中不断发现它会尝试将其发送到服务器...

现在的问题是如果服务器无法访问，那么它将打印该服务器不活动等。如果这个循环持续几分钟，脚本就会崩溃并显示分段错误......我想处理这个异常并想要处理一些如果发生分段错误

工作环境：linux python3 sql-server

编辑

这是脚本崩溃后显示的内容...

解决方案

好吧，我什至不知道分段错误是可能的，分段错误意味着您在内存中走得太远到未映射的地方。您应该注意最初发生问题的行并检查这些行。
