Sometimes a line in the IIS file is not written correctly, and you get missing columns or overlapping columns, and this can cause a problem. But using "text" will certainly eliminate the problem of data truncation.
After importing, you can always set up a new column named [cs (User-Agent) varchar], which is varchar (8000), and copy the data into it using convert (varchar (8000), [cs (User-Agent)])
