36727 Fix simple server problem

I need to have a server fixed. I know nothing about servers but I think it's the update cron that hangs or something like that. I receive the following email from the server: [login to view URL] Also, the server keeps starting "perlinstaller" processes that max out the cpu. It's a linux server with whm/cpanel. This error should be very simple to fix so I would also like a quick security check/fix.
