I'm getting "CSV parser got out of sync with chunker", any idea on how to troubleshoot this? 
If I feed the original file it fails after 1477218 rows 
if I remove the first line after the header then it fails after 2919443 rows  
if I remove the first 2 lines after the header  then it fails after 55339 rows
if I remove the first 3 lines after the header then it fails after 8200437 rows
if I remove the first 4 line after the header then if fails after 1866573 rows
To me it doesn't make sense, the failure shows at different, seemly random places.

What can be causing this?  source code below->
