Applies to:Oracle Net Services - Version 184.108.40.206 to 220.127.116.11 [Release 11.2 to 12.2]

This problem is limited to Unix platforms.
This problem occurs when a statically defined service handler of a higher version listener is used to connect to a lower version database. For example, a 18.104.22.168 listener servicing a 22.214.171.124 database.
The same clients connecting through dynamic service handlers work properly.
