It patched cleanly except for the version header. I've been running it for about 36 hours now with no problems. I'd say
thatI'm about 85% convinced that it made the difference, as I've also done some optimizations since then that reduce
thedatabase load by caching.  

I'd say that this patch is a candidate for 7.2.5 if there's ever another 7.2 release.

thanks for your help.
