I have seen the behavior once with my P6-200 worstation on 2.1R. It started one afternoon (a few days agon) after the machine had been up for days. Xterm windows and other more-or-less tty-looking things started updating in chunks every 1 second. I tried killing things (like the X server, etc...) and other diddling but only a reboot cured it. This has only happened once in several months of almost constant heavy use, but it was rather scary once it started.... ----------------------------------------------------------------------------- Robert Withrow, Tel: +1 617 592 8935, Net: witr@rwwa.COM
