XML-SAX parsing issue

I'm having this weird issue parsing XML. The XML is generated in-house on Windows and parses properly the vast majority of the time. I have the rare XML file where I lose all the data past some point. Here are some (hopefully) relevant code snippets.

.......................................................................................................................................................

XML-SAX %handler(cjfSaxHandler :handlerInfo)
%xml(FilePath :'doc=file ccsid=ucs2');
.......................................................................................................................................................
P*--------------------------------------------------
P* Procedure name: cjfSaxHandler
P* Purpose: Parse XML data for CJF
P* Returns: Return code
P*--------------------------------------------------
P cjfSaxHandler b
D pi 10i 0
D info LikeDs(gHandlerInfo)
D event 10i 0 Value
D stringPtr * Value
D stringLen 20i 0 Value
D exceptionId 10i 0 Value

Dcl-s charsUCS2 ucs2(65535) Based(stringPtr);
D chars s 65535a

chars = charsUCS2;
.......................................................................................................................................................


Debugging the code, the "chars = charsUCS2" statement works fine, until a point. From then on, chars is always blank even though charsUCS2 has a value. It appears that the XML events are working properly. I eye-balled the XML and I can't see anything wrong with it. I don't even know where to go with this.

Any ideas?
