Informix error in SSIS

Hi

I am running an SSIS package to extract the data from Informix into MS SQL server. It was working fine before but now it is giving me error for two tables after adding some more columns to two tables.

Before in those two tables there were 15 and 10 columns and now there are 27 and 45 columns resp.

ERROR:

[ADO_SRC [494]] Error: The component "ADO_SRC" (494) was unable to process the data. ERROR [HY008] [Informix][Informix ODBC Driver][Informix]Statement interrupted by user. sqlerrm(table_name)

any idea what causes this error??

Thanks
