Wait for unread message on broadcast channel during import

Question

Hi All,
I am trying to import a dump file on Oracle DB, Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi.
My import hangs, below is the log.
Import: Release 10.2.0.3.0 - 64bit Production on Tuesday, 03 April, 2012 21:09:20

With the Partitioning and Data Mining options

Processing object type SCHEMA_EXPORT/PRE_SCHEMA/PROCACT_SCHEMA
Processing object type SCHEMA_EXPORT/TABLE/TABLE
Processing object type SCHEMA_EXPORT/VIEW/VIEW
It doesn't proceed further.
I am not seeing and sessions blocked or locked but I see session waits.

and program like 'orac%'
and s.saddr = D.SADDR;
Below is the only message I see in alert log.

I have googled but haven't been able to resolve the issue.
Can anyone help me with this ?
Many Thanks

Kalaiproper invocation of procedure below will allow you to monitor progress
by observing contents of resultant trace file
DBMS_MONITOR.SESSION_TRACE_ENABLE(
    session_id   IN  BINARY_INTEGER DEFAULT NULL,
    serial_num   IN  BINARY_INTEGER DEFAULT NULL,
    waits        IN  BOOLEAN DEFAULT TRUE,
    binds        IN  BOOLEAN DEFAULT FALSE,
    plan_stat    IN  VARCHAR2 DEFAULT NULL);
