C ++应用程序以143退出代码终止-这是什么意思？

Question

My C++ application crashes periodically. It writes Terminated in terminal and stops. I have no idea what is the reason ( gdb is not solution, it is mutithreaded application, and error appears on big amount of threads only that gdb can not process due to its low performance). What does exit code 143 mean on CentOS Linux? Does it contain information about the reason of the crash?

Answer 1

143 usually means the application caught a SIGTERM signal, meaning the process was killed. This could be because another process killed it, or perhaps because the operating system killed it for using too much memory or some other resource, etc. Without more information, it's hard to know.

Answer 2

There are some exit codes which have either defined or generally agreed upon meaning.

In case of 143, which is 128 + 15, that means program died with signal 15, which is SIGTERM

According to the above table, exit codes 1 - 2, 126 - 165, and 255 have special meanings, and should therefore be avoided for user-specified exit parameters.

Answer 3

Error 143 means that the application is been killed by some other application or the OS itself. this error is due to many reasons such as performing some unauthorized operation ie exploiting user privileges, or the system cannot provide the required drive or directory ,or problem in DNS configuration, or in rare cases inexact float point result..but without sufficient information exact cause is hard to tell...
