Recently, I was working away as usual, and the fan on my Powerbook G4 came on (which it only does when I do something quite computationally intense, usually). Since i was just doing regular, non-intense stuff, I checked the CPU usage using Activity Monitor. An application that I have had for a long time was using up to 50% or more of CPU! This was strange because the application should not have even been running. It is a small application which is used to sign in to a single license of a very expensive software that I share with my co-workers. (So what it does is it calls the computer that has the single license and allows one user at a time to access the software). Anyways, i killed the process, (which was a root process) and restarted. Now, every time i restart, the process restarts itself and again takes up way too much CPU. I then used spotlight to search for everything with the process name and found that it has a folder listed in the library under startupitems, and it has a .plist there. Now, i don't know what the .plist is for, but is this what is causing the over-use of my CPU? Any advice on what i should do? I really don't think it is good to have so much CPU being used for no reason. I would greatly appreciate any advice or thoughts!! Thanks very much!
