Do your records include many many keys?

We were hit by a limit on the number of "keys" that AppleScript can store, those "keys" including the records' keys, all the variables' names and all the handlers' names.

This is easily tested:

--------
display dialog "ready to bug?"
repeat with i from 1 to 10000
	try
		run script "set r to {|" & i & "|:1}"
	on error -- Internal Table Overflow: your app is no longer usable, quit ASAP 
		display dialog i
		exit repeat
	end try
end repeat
--------

As it goes along it accumulates some information (title, abstract, filename, etc.) about each item in an Applescript record; at the end it read throughout the recoed and writes out a summary -- essentially a table of contents.

At first I though one of the Filemaker records was corrupted, but switching them around doesn't change the results. It seems as if Applescript is saying "Hey, I can only do so much of this and then I have to quit." The information read in from the Filemaker record presumably is overwritten each time, as it's assigned to the same Applescript variable. The best idea I can come up within that Applescript can only store so much information ion its own record. Or that the stuff being read in *doesn't* feet flushed.
