export (7.3.2) and import (9.2.0.4)

Hi,
I have been getting error during export(Oracle 7.3.2) and Import on (9.2.0.4).
When I used DIRECT=Y & recordlength export on 7.3.2 version works fine.But when I'm using same export file to import on Linux 9.2.0.4 it's showing following error
IMP-00020: long column too large for column buffer size (7) IMP-00018: partial import of previous table completed: 40500 rows imported
. . importing table "M_REPORT" 0 rows imported
. . importing table "APP_END_USER" 43683 rows imported
. . importing table "LI_APPLICATION"
IMP-00009: abnormal end of export file
IMP-00018: partial import of previous table completed: 595 rows imported

When I selecting that table on oracle 7.3.2 version with SUBMISSION_date COLUMN its showing error after 40500 rows. "RROR:
ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], []" No trace file generated.
ANALYZE works fine,dbv runs fine on those datafiles. I have tested all combination of DIRECT=Y ,COMPRESS=N & recordlength option but ONLY this options work fine during export but when I was importing noticed same error on same table.
the table select on source database on that table works fine without ONE columns SUBMISSION_DATE.Even select work fine uptol 40500 rows with submission_date.Noticed error after 40500 rows. RROR:
ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], []

please advice.
thanks
