Cause: High CPU usage can occur when multiple processes or high traffic overload the server. For example, running resource-intensive tasks like product data imports can degrade performance.

Impact: The app service plan may become maxed out, causing the application to respond slowly or fail.

Cause: Azure's auto-healing feature may restart an app if it detects slow responses or high CPU usage exceeding thresholds.

Impact: Temporary downtime may occur during the restart or instance switch.

Cause: Misconfigurations, such as an invalid path to the csproj file or incorrect rewrite rules in the web.config file, can lead to downtime or broken API links.

Impact: These issues can prevent the site from loading or cause redirection errors.

Cause: Sharing server resources with other applications can lead to resource contention, especially during peak usage times.

Impact: This can result in performance degradation or downtime.

Restarting the affected environment can often resolve temporary issues caused by resource contention or configuration errors.

Investigate the web.config file for misconfigurations, such as incorrect rewrite rules or invalid paths.

Use monitoring tools to track CPU and memory usage. Identify and address resource-intensive processes.

If Azure's auto-healing process is triggered, allow it to complete. The site will typically return to normal once the process is finished.

To avoid resource-sharing issues, consider moving to a dedicated server where you have exclusive access to resources.

Schedule resource-intensive tasks during off-peak hours to minimize their impact on site performance.

Ensure that all configuration files are correctly set up and updated to prevent errors.

Use Azure's monitoring tools to track resource usage and scale up the app service plan as needed to handle increased traffic or processes.
