CA API Gateway 10.x or 11.x Monthly platform patch patching results in many kernels

Products

• CA API Gateway

Issue/Introduction

It may be noticed that when consistently applying patches that

#rpm -qa | grep -i kernel

May return many, many results.

This could lead to

a) To many symbolic links errors with certain 3rd party software installed.

b) Disk space issues over time

c) CVE Detections based on old un-used un-loaded kernels. 

Environment

CA API Gateway 10.x and 11.x

Resolution

Currently the Monthly Platform patch (aka MPP) applies and utilizes the latest kernel but does not remove old kernels in case of any corruption or problems with the latest kernel allowing boot to older kernels. 

The MPP Will be enhanced to instead of keeping all older kernels to only keeping a smaller sub-set of older kernels which should alleviate any of the previously mentioned concerns. This is expected to be released in approx April/May 2024 Monthly Platform Patch.
