lfd on luna.fibercomet.com: System Integrity checking detected a modified system

So I removed memcached since I decided to go with redis-server instead with "yum remove memcached" and then I ran "yum autoremove" to clean up any left over dependencies. Then I received this email, so far everything appears to still be working, but this email is very concerning to me.  Should I be worried or is their a recovery path/command that I should run to restore any of these items that are important?

Not a CentOS 7 problem.
CSF is kindly notifying you that someone has made changes to core files (YOU).
Likely due to recompilation.

Thanks.  So just a notice message, because I removed things.

its due to update changes
