LFI-00102:

Unable to seek in sequentially accessed file.
Cause: The file was opened with the flag LFILFA_SEQ for sequential file operations. Use seek only on files that are opened with the LFILFA_RANDOM flag for random access.
Action: Check to see how the file is being opened and accessed and make the two operations consistent (that is, make them both operations either sequential or random).
