First, I realize this might not be the right group. Please feel free to redirect me :-) I recently upgraded from CentOS 5.6 to 6.0. Since the upgrade, Xvfb will, on occasion, "just stop" (ie the process disappears from the system, as opposed to still being there but not working). I can't find any tracks anywhere that it might have left behind that might be clues as to why it stopped. There's nothing in /var/log that looks promising (nothing in messages or Xorg.0.log). Any other clues about where to look or command line options I should add? Thanks in advance, Bruce
