The kernel exception error occurs due to the absence of driver files that match the operating system, with the root cause lying in the Linux kernel mechanism.
Kernel drivers need to be compiled on-site according to the specific Linux version to function properly. Although we have collected drivers for many versions, for some uncommon or newly updated kernel versions, on-site compilation is required.
Kernel exceptions will render modules such as tamper protection, process protection, and firewall ineffective. The solutions are as follows:
Method 1: Upgrade the System Kernel
The primary cause of kernel driver exceptions is an outdated kernel version. Therefore, it is recommended to first upgrade the kernel to the latest version and then "update the drivers."
1. Kernel Upgrade for CentOS Series
Execute the following commands and then restart the server:
yum upgrade kernel
Applicable CentOS series distributions include: CentOS, CentOS Stream, Alibaba Cloud Linux, TencentOS, AlmaLinux, and Rocky Linux.
2. Kernel Upgrade for Ubuntu/Debian
Execute the following commands one by one, and then restart the server:
apt update apt upgrade
If the upgrade fails, please execute the following command:
apt-get update apt-get upgrade
Method 2: Contact Customer Support for Assistance
If Method 1 does not resolve the issue, please reach out to our online customer support or submit a service ticket. Our engineers will compile the driver for you on-site.
When submitting a service ticket, please remember to include the server IP, remote port, account, and password. Additionally, ensure that the remote protection feature is turned off.
