We have an application managing Dicom files.
one Job of this application is to receive some XML Files and converts them to dicom for further processing.
To avoid re-inviting the wheel we spawn a process and use xml2dcm to do the conversion.
Generally that works fine and fast.
But sometimes after our application was started the first time when we try to import a XML file we have a strange behavior.
There is a private tag inside the XML file specified as unlimited text (EVR_UT)
and the conversion of that tag to DICOM only does happen if the text size is <= 4096. If the text is larger XML2DCM determines the right size and everything else seems to be converted correctly but it leaves the text empty and does not copy the text to the dcm file.
here is the element that failes

The most strange thing is that it only happens the First time we try to import the file.
Our application checks if the dicom file is already imported and only imports if not available. So a delete of the converted file and again an import and it will work correctly.
Does anyone have an idea what happens here?

I know this is not a completely XML2DCM problem, but may be someone here already had seen such behavior before.
I played a little bit with the CreateProcess to get the Output Dcm2xml writes to stdout /STDError, but it only reports that it generates the files. even with Verbose and debug no interesting output there.
Thanks in advance and
best regards
call so data that was larger than default size was not loaded. And that data was not loaded automatically before the it was stored.
