recursion limit exceeded (and seg faults with increased python recursion limit)

I believe there is an infinite loop in the recursion in the utils _do_resolve function. I have tried to replicate the issue from building out some of my own config files but haven't been able to do so. I have supplied our config file since its what is currently causing the issue in hopes that you have a better grasp than myself on what the issue might be.

Most of the Objects in this are either a LocalPlugin or RemotePlugin.
Some history behind our configuration file here. Our project is an open source Spring boot project (https://github.com/racker/salus-telemetry-monitor-management) and we are generating the swagger from https://github.com/kongchen/swagger-maven-plugin.
Github doesn't allow the uploading of yml files so I just changed the extension.
swagger.txt

Please let me know if you need more information or clarification from me.

Start by inspecting the utils _do_resolve function and use the attached swagger.txt configuration to investigate the recursion-limit failure. Confirm whether the input causes an infinite resolution loop, then verify that the configuration resolves without exhausting Python's recursion limit or segfaulting.
