Message size limit for communication component?

XML

I'm using the NAV Communication Component to transfer data from one NAV database to another (technical version 5.0 SP1). But it seems that the message arrives incomplete if it exceeds a certain size (about 107 KB).

The data is first exported by XMLPort to a temporary BLOB field, then loaded to an v6.0 Microsoft XML DOMDocument60 and the InStream for the Communication Message is then extracted from this DOM Document:

...
OutStream := OutMessage.GetStream;

CREATE(DOMDocument);
TempBlob.Blob.CREATEOUTSTREAM(BlobOutStream);
DataXMLPort.SETDESTINATION(BlobOutStream);
DataXMLPort.EXPORT;

TempBlob.Blob.CREATEINSTREAM(BlobInStream);
DOMDocument.load(BlobInStream);
DOMDocument.save(OutStream);

InMessage := OutMessage.SendWaitForReply(GetTimeout);
...

Receiving the message looks like this:

Communication Component Event trigger "Messag" has a VAR parameter InMessage.

InStream := InMessage.GetStream;
CREATE(DOMDocument);
DOMDocument.load(InStream);
...

On loading the InStream to the DOMDocument an error occurs that the Elements are not closed correctly as if the InStream was not transferred completely. I don't know why. Messages with less content are transferred perfectly.

Does anybody know if there is a size restriction for Communication Component messages?

The problem seems to be the DOMDocument which is not able to load the InStream of the InMessage correctly.
When the InStream is loaded directly into a File or imported to a Table by an XMLPort everything works fine - even if large content is transferred.
