Question

我已将gdb附加到一个长时间运行的进程（> 25小时）。为了管理会话，我在Ubuntu计算机上使用了屏幕。我可以找回会议。我回到了gdb控制台。但是在继续时，我看到我的流程抛出SIGABRT并退出，随后是其他流程退出消息。

[New LWP 122]

那之后，我无法获得gdb控制台。尽管我在运行ps -ef

时看到一个进程正在运行

root       133     0  1 Jan14 ?        00:26:09 gdb --pid=23

如何为该gdb进程找回控制台？我想看看回溯。还是有更好的方法将gdb附加到长时间运行的进程？

如何找回正在运行的gdb进程的控制台？
