I reviewed your logs and there is no entry for having either generated or validated a service ticket. This explains why you're not getting an LogoutRequest sent to your service -- you never authenticated to it from the perspective of CAS.
You should troubleshoot your client/server integration. You're looking for log entries like "Successfully granted ticket ST-ABC... for service https://some.example.com"; and "Successfully validated ticket ST-ABC...". Once you get those you should see a corresponding logout message where that ticket is send to the service via back channel POST.
