Do you notice a several second delay between when to end an X window process and when the window is deleted from the screen? If so, you might want to apply an HP X11 patch and see if that solves your problem.

Then the fact, that the size of X grows (but never decreases) is IMHO correct. The X server tries to cache what is on the screen, but does not give back the memory it needs for that. We saw the same on our AIX (3.2.5) boxes. We changed xdm on most (small memory) machines so that the X process restarts after a users logs out. This take some seconds, but then the X process has its original size for the new user. Prviously our machines really hung with 'Paging Space Low' and neede a reboot. The X restart solved our problem. You can do this by setting: DisplayManager._0.terminateServer: true in the xdm-config file (/usr/lib/X11/xdm/xdm-config on our machine) Hope that helps, Ralf -- Ralf Utermann ____________________________________________________________ _________ University of Augsburg (Germany), Institute of Physics Memmingerstr.6 "Speaking for me and nobody else" D-86135 Augsburg Phone: +49-821-5977-235 SMTP: Ralf.Utermann@Physik.Uni-Augsburg.DE Fax: -222
