SQL*Loader - Variable length field was truncated

Hi,

I am trying to load data from delimited file to Oracle via SQL*Loader. It gives me warning "Record 1: Warning on table <my_table>, column SYNOPSIS Variable length field was truncated.". All rows from the data file get loaded and that SYNOPSIS field gets truncated.
In my table it is a CLOB field where large piece of text stored.

Is there anything wrong in my SQL*Loader control file?

Thank you
