When deploying new code to production a Salesforce test function TestLearningData.createTestLearning is failing and preventing me from deploying new code

The error is: Failed to create createContainerMember for containerId=1dc5000000000lrAAA: This container member belongs to a container that currently has an unfinished save request with deploymentId=1drR00000001PF8. You may not modify any members in this container until it completes.: Metadata Container ID

I have waited for over 24 hours and it still comes up every time I try to save my Apex code.  What can I do to clear it out so I can save code again?  What does this mean or how can I avoid it  in the future.  

Thanks so much for any insight.  This has me dead in the road currently.
