I placed a script for killing all instances of the dataviewer program on the current computer in /cvs/cds/caltech/scripts/general/.  Its called killdataviewer.  This is intended to get rid of a bunch of zombie dataviewer processes quickly.  These processes get into this bad state when the dataviewer program is closed in any way other than the graphical menu File -> Exit option.

Its contents are very simple:

#/bin/bash

kill `ps -ef | grep dataviewer | grep -v grep | grep -v killdataviewer | awk '{print $2}'`
