The UnrealIRCd team does not officially provide support for any services packages that you may be using or want to use. This forum is provided so the community can help each other with services issues.
Uhm, 3.1.3 is 2.5 years old, we can't/don't support that... one can make it crash in like a thousand ways.
I suggest you to try 3.2.2. And if something isn't working, you can ask questions about it on the 'Unreal 3.2 Support' forum section. Be sure to spend some time reading the docs first, however.
