CMAN cmctl

Hello
I am trying to setup cman; After installing, i setup the cman.ora as per metalink / docs and tried starting the cmctl. I am ending up with TNS-04012: Unable to start Oracle Connection Manager instance. Metalink says there could be problem with cman.ora file. I don't see any syntax error (No difference is observed if the local listener on 1521 is running or not)
My cman.ora entry is
cman =
(configuration=
  (address=(protocol=tcp)(host=cmanhost)(port=1630))   (rule_list=
(rule=(src=cmanhost)(dst=127.0.0.1)(srv=cmon)(act=accept))
(rule=(src=cmanhost)(dst=dbhost.domain)(srv=GKTST)(act=accept))
  )
  (parameter_list =
(aso_authentication_filter=off)
(connection_statistics=yes)
(log_directory=/home/oracle/product/10.2.0/network/log)
(log_level=off)
(max_connections=256)
(idle_timeout=0)
(inbound_connect_timeout=0)
(session_timeout=0)
(outbound_connect_timeout=0)
(max_gateway_processes=16)
(min_gateway_processes=2)
(remote_admin=on)
(trace_directory=/home/oracle/product/10.2.0/network/log)
(trace_level=off)
(trace_timestamp=off)
(trace_filelen=1000)
(trace_fileno=1)
(max_cmctl_sessions=4)
(event_group=init_and_term,memory_ops)
  )
)

Any input on this would be appreciated.

Thanks
Govindan
