Oracle Locking Up

Oracle 9.2.0.1.0 on a single CPU 1.7GHz Pentium IV

One user doing SELECTS from various tables none with more than 10K rows and here's what I get:

SQL> select event, seconds_in_wait
  2 from v_$session_wait;

EVENT                                                  SECONDS_IN_WAIT

SQL*Net message from client                                        256

The lock up and these waits are outrageous. Any ideas will be appreciated.

It is a student's machine and I would like to try to fix the problem by email or phone rather than driving to their house.

Thanks.
