Hi all.
high RAM usage is typical but can be enormously reduced using google malloc
first install from http://goog-perftools.sourceforge.net/
google-perftools-devel-1.0-1.i386.rpm
google-perftools-1.0-1.i386.rpm
then in
/opt/glite/etc/init.d/glite-wms-wm
uncomment this line
#use_google_perf_tools=1
restart wm daemon
then RAM usage by WM should stay around 500MB
cheers
