My CPU usage on my MacMini Server has been at 100% for the past 3 days (see picture hopefully). The problem is it isn't doing anything, it supports a lab of 32 clients and none of them are being used (we are a high school). Should I be worried?

    Launch the Activity Monitor application when the CPU usage is spiking. Click the heading of the "% CPU" column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process?

    I see you have "SMB" running ... SMB is a Windows file sharing app, do you need it?  Go into the Server Admin "Settings" then  "Services" pulldown menus, UN-select all the services that you don't use (Server Admin automatically starts some (eg SMB) running), then restart your computer.  Massive CPU usage which shows up in the Actvity Monitor as PERL  probably is SMB.

    Hi there,


    I know this an old string but I've been having a similar problem with Perl eating 100% of my CPU at times. Did you ever solve this problem please? I'd like to hear what fix worked for you.


    Many thanks.
