Segmentation fault (core dumped) nginx

Segmentation fault (core dumped) error in NGINX usually occurs when there is a problem with the NGINX configuration or a bug in the software. Here are a few steps you can take to troubleshoot and resolve this issue:
1. Check the NGINX error logs: The error logs can provide useful information about the cause of the segmentation fault. You can find the error logs in the NGINX configuration file (usually located at /etc/nginx/nginx.conf) or in the system log file (e.g., /var/log/nginx/error.log). Look for any specific error messages or warnings that might indicate the cause of the issue.

2. Verify the NGINX configuration: Incorrect or conflicting configurations can lead to segmentation faults. Run the following command to validate your NGINX configuration file:

   nginx -t

This command checks the syntax of the configuration file and reports any errors or warnings. If there are any issues, you need to correct them before restarting NGINX.

3. Update NGINX: Segmentation faults can sometimes be caused by bugs in older versions of NGINX. Ensure that you are using the latest stable version of NGINX. You can check for updates using the package manager specific to your operating system.

4. Disable problematic modules: If you have recently enabled or updated any NGINX modules, they could be causing conflicts or crashes. Try disabling them one by one to identify if any specific module is causing the issue.

To disable a module, comment out or remove its corresponding configuration directive in the NGINX configuration file and then restart NGINX.

5. Check system resources: Insufficient system resources such as memory or disk space can also lead to segmentation faults. Ensure that your server has enough resources available to run NGINX smoothly.

If none of these steps solve the issue, you may need to seek further assistance from the NGINX community or consult with a system administrator or developer with expertise in NGINX troubleshooting.
