Hello, My system has suddenly become very unresponsive and when I run top, XFree86 reports that it is typically taking between 20-40% of the CPU, even when the machine is completely idle. 'ps aux' reports even more! (see below) Does anyone have any ideas what tools I can use to get to the bottom of this? I'm sorry to ask what may be obvious but I'm a relative newbie.. My machine is suddenly almost completely useless... Thank you! Nick ________ freedom# ps aux USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 11 76.0 0.0 0 12 ??
