CSV Engine Undocumented Limitations?

Can someone explain why I can 'see' ie. SELECT COUNT(*) FROM... only 2,209,217 rows of my 12,338,857 row CSV file? The file size is about 5GB (should that make a difference?), row size is around 450, all recs have the same len and all fields are fixed length CHARs. Are there some undocumented limitations at work here?

For what it's worth...
