Can this problem come from something else than a broken RAM?If it's not a RAM issue, I would advise to file a bug to your Linux vendor against httpd or php package, because RackTables has no means to crash its executing environment.
Just a thought, I'm not exactly sure what php libraries racktables use, but I've experienced segfaults due to GD failing (while using other php products). You could probably attach gdb (or strace or whatever) to one httpd and see what happens.
