12c: High memory and CPU usage with ocssd.bin

The My Oracle Support document "12c ocssd.bin high memory/CPU usage" via note ID 1965082.1 has shown up several times on the list of recently updated articles, so I figure tonight is a good time to make sure everybody is seeing this.  Make sure you apply this patch to prevent the 8MB an hour memory leak, and then investigate the other issues reported here on the AIX platform!
