问题
Unfortunately I don't have a specific question (or clues), but was hoping someone could point me in the right direction.
When I run all of my tests (rspec spec), I am getting two tests that fail specifically related to Delayed Job.
When I run this spec file in isolation (rspec ./spec/controllers/xxx_controller_spec.rb) all the tests pass...... Is this a common problem? What should I be looking for?
Thanks!

You are already mentioning it: isolation might be the solution. Usually I would guess that you have things in the database that are being changed and not cleaned up properly (or rather, are not not mocked properly).
In this case though I would suggest that, because the system is quite under a high workload, the delayed jobs are not being worked off fast enough. The challenge is with all asynchronous tasks that should be tested: you must not let the system run the delayed jobs, but mock the calls and just make sure that the delayed jobs have been received.
Sadly, with no examples, I can hardly point out the missing mocks. But make sure that all calls to delay_jobs and similar receive the correct data, but do not actually create and run those jobs - your specs will be faster, too. Make sure you isolate the function under test and not call external dependencies.
