Getting OAM-02073 when WebGate agent communicates to Oracle Access Server 11.1.2.3

Problem

In this particular scenario, you are trying to single sign-on an OHS server against OAM 11g. The products currently installed are Oracle Access Manager 11.1.2.3.0 and Oracle HTTP Server 11.1.1.9 with Oracle WebGate 11.1.2.1.0 deployed to it.

When we start up OHS, this error keeps repeating every 20 seconds in ohs1.log:

[2017-02-28T22:00:51.0079+00:00] [OHS] [ERROR:32] [OHS-9999] [core.c] [client_id: ::1] [host_id: toadsprod555555.com] [host_addr: 192.168.1.12] [tid: 140187036239616] [user: oracle] [ecid: 000Fzzx0g00009Ya05IPtKHC04Fw00000a] [rid: 0] [VirtualHost: main] The Access Server has returned a fatal error with no detailed information.

This also shows up in oblog.log:

This is the error that appears in oam_server1.out managed server log:
