[Wonder-disc] WO Stack Overflow in NSWeakMutableArray

[Randy W. <kr...@no...>]

I have a bulk process that reads through millions of rows of data  
processing.  Everything works fine for quite a few hours, but  
eventually this occurs.

Jul 27 16:25:59 - A fatal exception occurred:  
java.lang.StackOverflowError

Has anyone encountered this previously?  If so, can you provide any  
suggestions?  Unfortunately there is nothing at the top of this stack  
other than the NSWeakMutableArray references.  Any clue what is  
causing this?
