Solution :

Clear the /var/tmp/.oracle directory and start from fresh:

Stop all listeners
Remove the /var/tmp/.oracle directory, e.g. run the following from the root account:
```
rm -rf /var/tmp/.oracle
```
Check the listener(s) configuration contains unique keys specified for each IPC endpoint and each listener
Start the listener(s) from the normal Oracle OS user.

Clearing the /var/tmp/.oracle directory will force the listeners to recreate the socket files from fresh, each with its own correct ownership.
