We started deploying new VMs with SLES15.5, but now seeing zabbix alerts triggered for “apparmor.service: Service is not running”.

Can anyone shed light if changes were made to /etc/default/grub file to the SLES15.5 vm bare minimum image? As our systems running 15.1/2/3/4 have no alerts. It seems there was an option “security=” added to 15.5 /etc/default/grub… could not find anything noted in the release notes mentioning this update.

GRUB\_CMDLINE\_LINUX\_DEFAULT=“noresume security= crashkernel=334M,high crashkernel=72M,low elevator=noop mitigations=auto”

@goodyear_hosting Hi, it should be `security=apparmor`
