Hi Gurus,
I have a test rac configured on a linux machine which
has 3 instances running.
I am trying to test the TAF by crashing one of the
instance but client comes up with saying end of
communication channel
down below is the configuration I am using 
Can somebody please let me know as to where I have
gone wrong

Listener configuration

LISTENER_ORCL2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1523))
  )

SID_LIST_LISTENER_ORCL2 =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /opt/oracle/product/9.2.0)
      (SID_NAME = ORCL2)
    )
  )

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1521))
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /opt/oracle/product/9.2.0)
      (SID_NAME = ORCL1)
    )
  )

LISTENER_ORCL3 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1524))
  )

SID_LIST_LISTENER_ORCL3 =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /opt/oracle/product/9.2.0)
      (SID_NAME = ORCL3)
    )
  )

Tnsnames

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1523))
      (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST =
linuxtest2pub)(PORT = 1524))
      (LOAD_BALANCE = yes)
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
      (failover_mode=
        (type=select)
        (mode=basic)
        (retries=20)
        (delay=10)
      )
    )
  )

Init parameter entries

orcl1.local_listener="(address=(protocol=tcp)(host=linuxtest2)(port=1521))"
orcl1.remote_listener=
"(address=(protocol=tcp)(host=linuxtest2)(port=1521))"
orcl2.local_listener="(address=(protocol=tcp)(host=linuxtest2)(port=1523))"
orcl2.remote_listener=
"(address=(protocol=tcp)(host=linuxtest2)(port=1524))"
orcl3.local_listener="(address=(protocol=tcp)(host=linuxtest2)(port=1524))"
orcl3.remote_listener="(address=(protocol=tcp)(host=linuxtest2)(port=1523))"

The TAF works fine when I use only two instances
dont know where I have gone wrong.
Thanks in advance.
Arun
