Xvnc eating cpu randomly

[Ray Hall]

Hello,

I have a situation where the Xvnc process will consume the cpu on client exit.
This happens randomly, but can be produced within about 5 to 10 minutes of
opening and closing a session.

System and software

Dell PowerEdge 2600 run RedHat Linux 7.3 2.4.18 kernel
vnc-server-3.3.3r2-28.2
tightvnc-1.2.9 client and have also tried other vnc clients

Xvnc sessions are started through the Xservers file in /etc/X11/xdm/  below is
an example:

# $Xorg: Xserv.ws.cpp,v 1.3 2000/08/17 19:54:17 cpqbld Exp $
#
# Xservers file, workstation prototype
#
# This file should contain an entry to start the server on the
# local display; if you have more than one display (not screen),
# you can add entries to the list (one per line).  If you also
# have some X terminals connected which do not support XDMCP,
# you can add them here as well.  Each X terminal line should
# look like:
#       XTerminalName:0 foreign
#
:0 local /usr/X11R6/bin/X
:1 local /usr/bin/Xvnc :1 -nevershared -desktop VNC_1 -depth 8 -geometry
800x600
:2 local /usr/bin/Xvnc :2 -nevershared -desktop VNC_2 -depth 8 -geometry
800x600
:3 local /usr/bin/Xvnc :3 -nevershared -desktop VNC_3 -depth 8 -geometry
800x600
:4 local /usr/bin/Xvnc :4 -nevershared -desktop VNC_4 -depth 8 -geometry
800x600
:5 local /usr/bin/Xvnc :5 -nevershared -desktop VNC_5 -depth 8 -geometry
1024x768

Any help would be very much appreciated!

Thanks
