The usual cause is an incompatible audio program such as used by MIDI devices, M-Audio, or from installing third-party sound enhancement software like Hear or SRS WOW that is not fully compatible.
Double-click on the UserEventAgent entry in Activity Monitor. Click on the Open Files tab in the resulting window and scroll through the content listed to see what third-party software is running. That should identify the culprit. If you quit that software or force quit via Activity Monitor, then the problem with UserEventAgent should stop. If it does then remove the offending software and contact the developer to report the problem so the software can be updated. Until then the problem will recur when you use that software. Generally I've never noticed anything abnormal happen when I discovered this on my computer running older versions of Hear. Can't speak for other audio software.Mac Pro 2.66 Ghz; MBP Unibody; MBP C2D 2.33 Ghz; MBP 2.16 Ghz, Mac OS X (10.6.1), iMac C2D 17"; MB 2.0 Ghz; 80GB iPod Video; iPod Touch; iPod Nano 2GB
