Line sequential buffer length (Informatica)

I've configure Line sequential buffer length parameter to 4096 in my session.In my log session file I've this :FR_3071 Maximum Line sequential buffer length is 4098.
I don't understand what this line mean ?
Note: Query was taken from a Informatica related forum.
Reason:
Suppose you take below sample record as your input feed.
"7525 XX XXXXXX*0*10S*QQQQ*XX*YYY YYYY*US*USD*Common Stock*N.A.*XXXXX*JT*N.A.* *Machinery-Diversified"
Total length of the record is 104 characters (Bytes) and suppose if you have defined the "Line sequential buffer length" parameter to 100,then session would fail for
FR_3071 Maximum Line sequential buffer length is 100. (6.x/7.x version)
FR_3093 Record length [104] is longer than line sequential buffer length [100]. (From 8.x version)
How to calculate Line sequential buffer length:
Some how you need to find out the expected maximum record length and add 30% more, define that as a value for "Line sequential buffer length", just to neutralize a common solution irrespective of your code page setting. Because the way length of a character treated in ASCII and UNICODE are different.
Solution:
To avoid the above error change your default setting for "Line sequential buffer length".
Open the session properties.
Go to the General tab.
Select the Advanced Options button in the lower left corner.
Increase the Line Sequential Buffer Length setting so that it is larger than the largest row in the source file (including the header row).

What if you get a flat file that has no line feed (LF) or carriage return (CR) characters to mark the end of the record ?
1. Define a fixed width source definition.
2. Set Line Sequential buffer length to the length of the record.
3. In the flat file properties set the Number of Bytes to Skip Between Records to 0.
