pspace,
You can check your httpd service if your using prefork or worker by typing
httpd -V and look for
"-D APACHE_MPM_DIR="server/mpm/prefork"
that means your using prefork. if your MPM is worker then adjust instead of the prefork
<IfModule prefork.c>
StartServers 16
MinSpareServers 16
MaxSpareServers 64
ServerLimit 512
MaxClients 512
MaxRequestsPerChild 4000
</IfModule>
Bigger settings doesnt mean good for server. Your settings is a bloated at prefork settings and also workers MPM.
Please take a look at this site. or research more in performance tuning.
(dv) HOWTO: Basic Apache performance tuning (httpd))
Just to give you idea, 1 httpd process sometimes consumes about 128 MB of your memory and based on your settings if you started 16 httpd process(startservers) multply by 128 MB plus additional 16 more (min spare) thats a lot of memory consumption. I never include the max clients that is allowed.
So bigger is not always good for settings in apache.conf. You can google for apache performance to look for more answer. Cheers

xmdropsiteconfigurestackingorder
XmDropSiteConfigureStackingOrder(library call) XmDropSiteConfigureStackingOrder(library call)
NAME
XmDropSiteConfigureStackingOrder -- A Drag and Drop function that reorders a stack of widgets that are registered drop sites
SYNOPSIS
#include <Xm/DragDrop.h>
void XmDropSiteConfigureStackingOrder(
Widget widget,
Widget sibling,
Cardinal stack_mode);
DESCRIPTION
XmDropSiteConfigureStackingOrder changes the stacking order of the drop site specified by widget. The stacking order controls the manner in
which drag-under effects are clipped by overlapping siblings, regardless of whether they are active. The stack mode is relative either to
the entire stack, or to another drop site within the stack. The stack order can be modified only if the drop sites are siblings in both the
widget and drop site hierarchy, and the widget parent of the drop sites is registered as a composite drop site.
widget Specifies the drop site to be restacked.
sibling Specifies a sibling drop site for stacking operations. If specified, then widget is restacked relative to this drop site's stack
position.
stack_mode
Specifies the new stack position for the specified widget. The values are XmABOVE and XmBELOW. If a sibling is specified, then
widget is restacked as follows:
XmABOVE The widget is placed just above the sibling.
XmBELOW The widget is placed just below the sibling.
If the sibling parameter is not specified, then widget is restacked as follows:
XmABOVE The widget is placed at the top of the stack.
XmBELOW The widget is placed at the bottom of the stack.
For a complete definition of DropSite and its associated resources, see XmDropSite(3).
