Does your XPe have Perfmon available? Nearly all the issues I've seen with embedded XP turned out to be due to a lack of memory (even the disk and cached changes use memory, right?) and the symptoms were typically hangs or crashes from code.
What can code do if it gets "no memory" results from APIs? I suspect much of it reacts badly (or at least doesn't or can't tell you about it).
