Crashed Linux TCP Program Performance Crash Analysis

As a Linux administrator, the most worrying problem is the crash of the system, especially the crash of the TCP program. It is necessary to diagnose the cause of the crash in time and improve the stability of the system. In this article, we’ll discuss the performance crash analysis of a typical Linux TCP program.

It needs to be emphasized that crashing is because the real environment is too complex, making it hard to determine the real cause. Therefore, a precise analysis should be made after obtaining sufficient conditions.

The first step is to determine whether the crash is related to hardware or software. Generally speaking, the hardware reasons are easier to detect. If the system or hardware often crashes or has other abnormal shutdown problems, we may suspect that the hardware isn’t working properly. On the other hand, if the hardware is functioning normally, we can focus on troubleshooting software problems. We can use commands such as strace, gdb and lsof to diagnose the software.

The second step is to determine whether the crash is related to the source code of the application itself or an external library. If we think the crash is related to the source code of the application, we have to analyze the source code. Once you identify the suspicious function, fill in the code for logging related information and recompiling the code until you can observe the output.

The last step is to determine the cause of the software crash and improve it. According to the output from the logs, we can quickly determine the causes of the crash. Take a web application for example, the system crash may be caused by too much concurrent connections, errors in connection parameters, SQL statement errors, etc. After determining the specific causes, we can optimize the system based on the cause.

In this article, we’ve discussed the performance crash analysis of a typical Linux TCP program. Although it’s difficult to determine the cause in the real environment, we must keep trying until the crash can be determined and resolved. In the process, we need to rely on tools such as strace, gdb and lsof to monitor system performance and diagnose the cause of the crash.
