Thanks for helping! Per your post, I've researched the 'prefork MPM' section of my httpd.conf file but am not finding anything that helps me fine tune the settings for my particular server usage or server type.
I believe I saw some example .conf files that were like htppd-huge.conf htppd-large.conf htppd-small.conf and stuff like that. I went through each saw that the huge one was referring to a server with 4GB ram which is what mine has. I tried using those settings but my server didn't like it very much at all! Next I tried using the large and medium ones but again my server acted funny so I reverted back to what I have:
There must be a way to limit the CPU usage of each httpd thread so that it doesn't reach 100% ? I read doc's on the Apache site that explained what each of the above does but it didn't help me figure out which way to go with things. Do I leave the worker.c alone above and focus on the prefork? You said to modify the FF but I don't know what FF stands for sorry. You pasted MaxClients, etc. so I'm assuming it's the prefork I should mess with.
Another thing that I tried was since the huge .conf file example had settings almost double mine, I attempted to double the settings such as changing StartServers to 32 from 16, all the way down the module list. That didn't work either.
We have more than 2GB of RAM that's not being used since Plesk usually says we're using between 1GB and 2GB, so I don't imagine this is memory related. Also since most threads in TOP show 0.3% cpu usage to 1.7%cpu usage, it seems to be a problem when I find 100% usage. For instance I got home an hour ago and killed 5 threads that were 100% cpu usage in TOP. I just checked now and see 2 more running and bogging down my server. There's a big difference between 0.6% and 100% I'd say Any further help for my confusion would be GREATLY appreciated!
CPU usage: PS versus TOP - Different output
Hi
When monitoring a Linux environment with PS command, reported CPU value for a certain process differs, sometimes greatly, from the value seen in TOP.
I understood this is not a bug, they report different data.

I am running a Dell PE R815 with 4 x AMD 12 core CPUs with 128GB of RAM and a RAID 5 array of 6 SAS disks. This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...

XmDropSiteRegister(3X)XmDropSiteRegister(3X)NAME
XmDropSiteRegister - A Drag and Drop function that identifies a drop site and assigns resources that specify its behavior
SYNOPSIS
#include <Xm/DragDrop.h>
void XmDropSiteRegister (widget, arglist, argcount)
Widget widget;
ArgList arglist;
Cardinal argcount;
DESCRIPTION
XmDropSiteRegister identifies the specified widget or gadget as a drop site and sets resource values that define the drop site's behavior.
The routine assigns default values to any resources that are not specified in the argument list. The toolkit generates a warning message if
a drop site is registered with XmNdropSiteActivity set to XmDROP_SITE_ACTIVE and the XmNdropProc resource is NULL.
If the drop site is a descendant of a widget that is registered as a drop site, the XmNdropSiteType resource of the ancestor drop site must
be specified as XmDROP_SITE_COMPOSITE. The ancestor must be registered before the descendant. The drop site is stacked above all other
sibling drop sites already registered. Specifies the ID of the widget to be registered. Specifies the argument list. Specifies the num-
ber of attribute/value pairs in the argument list (arglist).
For a complete definition of DropSite and its associated resources, see XmDropSite(3X).
