Size Limits / know issues with XML-INTO?

All,

Is there any kind of limits or known issues to the size of an XML doc that
can be processed using the handler version of XML-INTO?

I've got some code...
XML-INTO %HANDLER(#PartMasterLine : allOk)
%XML(%TRIM(WpIfsFile) : %trim($OPTIONS));

The #PartMasterLine is a DIM(20) data structure...

I process about 600,000 elements (75-80% or so) successfully...

Then get a

RNX0353 - The XML document does not match the RPG variable; reason
code 5.

Cause . . . . . : While parsing an XML document, the parser found
that the XML document does not correspond to RPG variable "PARM" and
the options do not allow for this. The reason code is 5. The exact
subfield for which the error was detected is
"PARM(1).returnindicator". The options are "doc=file
path=ShowPartsMaster/ShowPartsMasterDataArea/PartMaster/PartMasterLine
case=any ns=remove datasubf=Data allowextra=yes allowmissing=yes".


5. The XML document contains extra XML attributes or elements that do
not match subfields.



Now, I've added some code and even changed the DIM(20) to a DIM(1) so
that I can better understand where the problem is..


Looking at the XML, starting from the last successfully processed
PartMasterLine, I don't see any problems...


And if I remove about half the data (from ~1.5GB to ~700MB) from the
beginning, the remaining data processes without issue...


I've tried "minifying" the XML and I get further into the doc, but
still get the error.


Also have tried new versions of the doc, same problem.


The one constant, the error gets thrown at approximately the 1GB mark
into whatever document.


I've got a case open with IBM, but I thought I'd through this out here
to see if anybody else has seen a similar issue.


We running 7.2 and are pretty up to date on PTFs.


Thanks!
