Flat File Source truncates Data

Hey,

I am trying to read a flat file of 17,2 MB data and write it into a SQL table as a XML file. The flat file source is a .nbits file and i read the whole file as one row with data type DT_TEXT. I try to transform the source data to unicode and write it into the SQL table as xml data type. The last step fails reporting following description: "XML parsing: line 147914, character 30, unexpected end of input."

While debugging i tried to read the flat file source and write it directly back into another file, resulting that the written file has only 8 MB instead of the expected 17,2 MB.

Why does the data gets truncated?
