Problem with SQL loader - "maximum length"

Question

using SQL*Loader: Release 8.1.7.0.0
===================================
(full CTL enclosed below)
I have a problem with several rows, in which I'm getting the "Field in data file exceeds maximum length" error.
the DB field (referer) is a VARCHAR2(4000), and the field in the error rows never exceeds few hundred characters. According to Oracle docs I should be able to load fields which are no bigger than the DB field, what gives?
I tried the variation
referer CHAR "SUBSTR(:referer,1,100)"
for this field, which causes all the "referer" columns in the "good" rows to load no more than 100 characters, but the same error repeats for the same rows!
the input file is an IIS log, and the field is the REFERER field. its pure ASCII encoded, is there some character that cause Oracle to behave this way? is this a bug?
here is one "bad" row: the "bad" field starts with "ht
tp://web , is enclosed with quotes. I have replaced the client IP and other fields with xxx for privacy reasons.
after that, I have enclosed my CTL as well.
any help ?

BTW - I verified in the LOG file that the loader is reading my options for the columns as I described in the CTL. no problem there.

Answer 1

Use:
readsize=3000000
or some large number to raise this limit.
