Plesk Critical Errors: How to Fix Kernel Panic?

Critical Error: What is Kernel Panic?

Kernel panic occurs when the Linux kernel detects a serious error, stopping the system and displaying an error message to the user. It is often caused by hardware failures, incompatible drivers, or errors in kernel configuration.

Causes of Kernel Panic

• Hardware failures (RAM, hard drive)
• Incompatible or faulty drivers
• Kernel configuration errors
• Insufficient memory

Step-by-Step Solution Guide

Follow these steps to resolve the kernel panic issue:

1. Connect to the Server via SSH

First, connect to your system via SSH:

ssh root@server_ip_address

2. Review the Error Message

The kernel panic error usually occurs during server boot. Therefore, record the error message that appears on the screen during boot. This message is important for determining the source of the problem.

3. Perform Hardware Check

Ensure that the hardware is functioning properly. Check the RAM and other components:

memtest86+

You can test your RAM with this command. If any errors are found, replace the RAM modules.

4. Update Drivers and Kernel

Kernel panic errors can sometimes stem from incompatible drivers. To install the latest drivers:

apt update && apt upgrade

5. Check Kernel Configuration

Check your kernel configuration. Examine the kernel files in the /boot directory:

ls /boot

If there are old kernel files, remove them:

apt remove linux-image-old_version

6. Review Log Files

Check log files to find the source of the error:

cat /var/log/syslog

or

dmesg

7. Restart the System

After performing all checks, restart the system:

reboot

8. Restore or Reinstall

If the problem persists, consider system restoration or reinstalling the operating system. Check your backups and perform a restore.

Conclusion

Kernel panic errors can cause serious issues on your server. By following the steps above, you can resolve this issue and keep your server running securely. Remember, regular backups and updates help prevent such problems.
