BAM! Crashing servers since 1999 :-D - I'd bet its the DOM - I think
cfmx likes to make DOMs out of xml and that means a grip of memory.
Tonight I'll modify the sheet to only do 1 list, but I think it might be
3.9 Megs
<cffile action="" file="#path1#" variable="myxml">
+3.9 Megs times about 3 (for the in memory tree)
<cfset mydoc = XmlParse(myxml)>
Don't know if that is SAX or not, so it could be another
+XX Megs for the result tree
<cfset transformedXML = XmlTransform(mydoc, xslDoc)>
We'll play tonight
Cheers,
