A small schema from 120 GB export could not be imported

Question

Dear,
could you please be so kind and advice me what could be a problem for the following issue?
I have 8.1.7 database on W2K (it is a shame, bit it is not a topic of my question) and I have to import one schema from 120 GB export done successfully few days ago. How to say - very simple task. So, I created the different user (e.g. TARGET_USER) in database, granted connect, resource privileges, and let me go:
cmd> set ORACLE_SID=SID
cmd> imp userid=sys fromuser=SOURCE_USER touser=TARGET_USER file=120_GB_export.dmp log=imp.log
So, import takes some time, I observe in task manager number of data read by IMP.EXE program. When the value reaches about 80 GB at about all tables are imported and then import goes on. When the number of data read from disk (values in task manager) reaches about 95% of export size the process hangs.
Checking in database: a) session is INACTIVE, b) in V$SESSION_WAIT I could find the following event: SQL*NET message from client, SECONDS_IN_WAIT increasing to minutes, hours and does not finish.
Have you any idea?
Kind Regards, Piotr

Try importing just the data first and re-create the indexes later.
Monitor the import process using,
SELECT
SUBSTR(sql_text, INSTR(sql_text,'INTO "'),30) table_name
, rows_processed
, ROUND( (sysdate-TO_DATE(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60,1) minutes
, TRUNC(rows_processed/((sysdate-to_date(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60)) rows_per_minute
FROM
sys.v_$sqlarea
WHERE
sql_text like 'INSERT %INTO "%'
AND command_type = 2
AND open_versions > 0;
check the alert.log for any errors reported.
