I get a "[server.server.com] DISKWARN blocks ?: Mount Point "/boot" (212.25.xxx.xxx): 164.19 MB/496.67 MB - 33.057799%" warning email from cPanel all the time. Where do I disable this?

  What do you have set at WHM>>Server Configuration>>Tweak Settings -> Account system disk usage "warn" percentage Threshold percentage to warn the system admin (via email) that the system disk usage is considered to be in the "warn" state.

  Hi, I have the same issue. I don't know much about servers. I don't worry about warnings, I worry about finding a solution for this issue. Can I add more space to /boot? Is it normal for a server to have 91% of its /boot? Is there any way to make sure this issue doesn't become a problem in the near future? Thanks for your help!

  Whether or not you know much about servers if you are someone who is an admin for one you should definitely worry about warnings and why you're receiving them. As far as adding space goes, generally speaking, you cannot add space to a mount point the exceptions to this would be an instance where you're on a Virtual Server and you can extend your partition, though this would be best handled by a professional. The /boot mount size really shouldn't fluctuate much what's probably occurring is there are old kernel versions there that have not been removed. You'd need to go to /boot
  and look at what's there to confirm this though.

  Lauren, thanks for your answer. this is all I have at /boot. Could you guide me about removing old kernel versions, if possible? Thanks again!

  Hello, They should be removed automatically and that's really the part you need to be addressing. First you'd want to install yum-utils or make sure it is already installed: To check for it you would do: rpm -qa |grep yum-utils
  If it's not there to install it you would run: yum install yum-utils
  The following will remove all old kernels except for the latest 2 (you should always have the one you're using and one prior in the event of a kernel issue) package-cleanup --oldkernels --count=2
  Do that and let me know how much space that cleared up for you, if you could.

  Now that this is probably more of a non-emergency status, for the rest of the items listed there I'd suggest you touch base with your provider to have the rest of those packages listed there evaluated
