Hi, hope this is the right place to ask this: I got this strange problem. One of our computers keep frozen after being used for a while, you still can move the mouse, but can't click, can't switch console. But I can login remotelly and running programes. The 'top' shows application X is running all the time at 100%CPU time. Checked all the log files, found nothing strange or maybe I missed something. Really don't know where to look. Any suggestions are highly appreciated! Here the information about the system: Dell precision workstation 620 with 512MB memory, 1 cpu RedHat Linux 7.3 XFree86 Version 4.2.1 nVidia 256MB GeForce Fx5600 Thanks!
