TPT Export Error TPT01403

Hello, 
I am trying to export data from a Teradata table wm_ad_hoc.Table1 using TPT to a delemited file format in  UNIX. That table has around 11 million rows and the export works fine using BTEQ.
But when used TPT, only 8 million rows got exported and then errored out with the message
"TPT_INFRA: TPT01403: Error: Unable to write data to the file (fileHandle: 3), System errno: 9 (Bad file descriptor)".
Please help me in  resolvng this error.
Thanks,
stat
