[check_cpanel_rpms] Altered RPMs found on....

Hi I aploigise in advance - I would consider myself a beginner:

I have had this email sent to me at 02:24:

Problems were detected with cPanel-provided files which are RPM controlled.
If you did not make these changes intentionally, you can correct them by running:

> /usr/local/cpanel/scripts/check_cpanel_rpms --fix

The following RPMs are found to be altered from their original install state:
bandmin,1.6.1,9.cp1136,/var/log/bandwidth


Then at another email was sent to me at 06.05:

The file system /dev/md127p1, which is mounted at /boot, has reached warn status because it is 87% full.

Server: [i've removed this]

Is this an important warning and is this a common issue or some fault? I would be grateful of the community's support.

 

Thank you okay let's focus on issue 1.

What happens if I choose to ignore this command? Is it critical that I run this as the website seems to be fine?

My main worry is that if I run this it will cause me downtime? Is this true?
