On 10.2.x (On UNIX platforms):

- Trying to start extproc listener as non-'oracle' user
- lsnrctl hangs and the tnslsnr process spins (consumes excessive cpu).
- Works fine when started as the 'oracle' user.
- No errors as such just spinning/hanging and inabillity to connect to extproc listener.

- Listener log file indicates that listener has started.
- On node that works the listener log also contains the message:
'Listener completed notification to CRS on start'.
- This doesn't appear on node with problem.
- Trace file also indicates that the listener is trying to contact CRS. As not using RAC.
- Trying workaround of the bug 4518443 by setting:
'SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name>=OFF', but problem still occurs.
