Issue when parsing a large XML file and mapping to a csv file

Hello,

we have some issue to write a large file on our fileStystem. We are using webmethods 9.9.
The context :
We have a large XML file that we want to parse and map the field into a csv file. we use the getXMLNode service with the movingWindow set to “true”. The XML file is correctly parse until the line 999 999 then the process is stopped with no error and no log information. The number of line written in our file is always 999 999.
This process works on another Integration Server but we don’t understand what are the differences between these two environments.

Could someone help us please?

Best Regards,
Jeff
