Bug 36326543

On Oracle Linux 9.2, the listener fails to start due to issues with getaddrinfo() if the /etc/hosts has an entry in the order IPv4 and IPv6 addresses when the same host name and listener are configured with IPv6 address and ip=v6_only.

Workaround

Change the order of the address in the /etc/hosts entry with IPv6 first and then IPv4.
