Reasons and solutions for golang to stop output
Go language is a very powerful development language suitable for large-scale applications. It has efficient concurrency and excellent performance, but we may encounter some problems during use. One of the common problems is that golang stops outputting. In this article, we will discuss why golang stops outputting and how to fix it.
- Cause
In golang, there may be many reasons why the program stops outputting. The following are some of the most common reasons:
1.1 Code infinite loop
The infinite loop refers to the program falling into an infinite loop. This means that the program will continue to execute the same loop over and over again without being able to exit. If there are no correct conditions in the loop body to terminate the loop, the program will never stop outputting.
1.2 Memory Leak
Memory leak means that some resources in the program are not released correctly. In golang, the garbage collector automatically reclaims memory when variables are no longer used. If there are unreleased resources in the program, it will eventually cause the memory usage to continue to increase, eventually causing the program to stop outputting.
1.3 Process zombie
In golang, process zombie may occur. When a program is waiting for a resource, if the resource cannot meet the demand, the program will wait forever, eventually causing the program to stop outputting.
- Solution
2.1 Add logs to the code
During the development process, we can add logs to the code. This helps us find problems in the code and determine where the program stops outputting.
2.2 Use go vet
The go vet tool that comes with the Go language can help us find errors in the code, such as infinite loops, memory leaks and other issues. Go vet can be used through the following command:
go vet <package-name>
2.3 Using gdb
GDB is a powerful debugger that can be used to debug golang programs. You can add breakpoints to the program, control the execution flow of the program through gdb, and analyze where the program stops outputting.
2.4 Use profiler
The pprof tool that comes with Golang can help us analyze the performance bottlenecks of the program and determine the bottlenecks of the program through the performance analysis chart.
- Summary
In golang development, stopping output is usually caused by problems such as code infinite loops, memory leaks, and process zombies. In order to solve these problems, we can use tools such as logs, go vet, gdb and profiler to debug and optimize the program. Through the above methods, we can more accurately determine the problems of golang programs and solve them in time.

OpenSSL, as an open source library widely used in secure communications, provides encryption algorithms, keys and certificate management functions. However, there are some known security vulnerabilities in its historical version, some of which are extremely harmful. This article will focus on common vulnerabilities and response measures for OpenSSL in Debian systems. DebianOpenSSL known vulnerabilities: OpenSSL has experienced several serious vulnerabilities, such as: Heart Bleeding Vulnerability (CVE-2014-0160): This vulnerability affects OpenSSL 1.0.1 to 1.0.1f and 1.0.2 to 1.0.2 beta versions. An attacker can use this vulnerability to unauthorized read sensitive information on the server, including encryption keys, etc.
