Error: system is already running XXXX when execute STAP installer

Problem

The database server kernel was recently updated and we tried to upgrade STAP using the latest installer as our client does not use GIM. On executing, the following error messages was returned: [root@centos7a tmp]# ./guard-stap-9.0.0_r90265_v90_4-rhel-7-linux-x86_64.sh Verifying archive integrity... All good. Uncompressing guard-stap............................................................................. TARGET_TAG=9.0.0_r90265_v90_1 TARGET_PROCESSOR=x86_64 BUILD_BUILD=90265 Script appears compatible with this system. Installer is 9.0.0_r90265_v90_1-linux-rhel-7-x86_64 Detected previous STAP installation Do you want to update the previous STAP installation?
