Troubleshooting

In the history of C++ development projects, we utilized a custom protocol for communication, which employed a two-dimensional array pattern. When processing large volumes of data, the protocol required iterating through the arrays and performing serialization operations to generate logs. Due to its low efficiency, this resulted in noticeable lag or stuttering within the system under heavy load, as reported by the business departments. Problem Identification When troubleshooting the issue, we first performed a performance analysis of the system and discovered that CPU utilization increased significantly when processing large amounts of data, and system response times became longer.

Picking up where we left off, I discovered that GitHub had an update, which was a little exciting. The customer service team said the issue with the driver not loading properly was resolved. However, after going through all of this – reinstalling and uninstalling – it still wasn’t working correctly. Background Continuing to contact customer service to inquire about a resolution, I was informed that

Want your home network to be lightning fast? The key is understanding cable selection, optical terminals (ONTs), and router configuration, as well as those seemingly insignificant details. This blog post will guide you through easily learning how to build a gigabit network using six types of cables, and how to ensure your network speed isn’t restricted by simple device checks and configurations. Let’s explore together and make your home network fly!

When developing desktop applications, particularly when using the Windows Presentation Foundation (WPF) framework to build rich client applications, properly handling the user interface (UI) thread is crucial for ensuring the application’s smoothness and responsiveness. The UI thread, also known as the main thread, is the core thread responsible for processing window and control events, layout calculations, and rendering the UI. Any interaction with UI elements should be executed on the UI thread; this is a fundamental principle followed by WPF and most other GUI frameworks.

In the same business code scenario, the program compiled and ran normally in a CentOS 7 environment. However, when switching to CentOS 8 and using an updated version of GCC for compilation, the program crashed. It’s worth noting that the issue only occurs in Release mode, while Debug mode does not exhibit any problems. This is the first time we’ve encountered a situation like this; after three days of investigation, we finally identified the root cause.

Background: The business system, running in Windows version, is deployed locally and consumes approximately 5% of CPU resources. The Linux version of the business system, deployed within a VMware-installed CentOS8 environment, exhibits abnormal resource consumption. Problem Description Host Machine: Windows 10 Enterprise VMware: 17.5 Virtual Machine: CentOS8 The virtual machine resource allocation is 4C8GB, running the business system. The business system is deployed in the Linux system within the virtual machine, and the internal top command observes system resource usage.

In software development and operations, deadlocked processes are frequently encountered. This situation can lead to performance degradation or service unavailability. This article introduces how to use the pstack tool to troubleshoot deadlocked process issues by analyzing process stack information to identify the root cause and resolve it. Background: A child service within the risk control system experienced a deadlocked state, resulting in the unavailability of the risk control service. Due to the lack of service availability monitoring, the deadlocked process situation was not detected in a timely manner, leading to system unavailability.
