   It's not completely related, but I had a different error message and Google lead me here. So in the hopes that it will help anyone in my boat:
   
   I was/am having this issue on macOS Mojave version 10.14.6 running airflow locally and trying to get it to run tasks on Amazon ECS/Fargate.
   
   In the logs, I'd get the error:
   
   ```
   {local_task_job.py:102} INFO - Task exited with return code Negsignal.SIGABRT
   ```
   
   After a lot of Google, someone suggested trying to `$ export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES`, and that seems to have worked.
   
   The airflow scheduler running locally also hints at this: 
   
   ```
   objc[70653]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called.
   objc[70653]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
   ```
   
   Sorry for commenting at a closed issue, but I hope this can help anyone having the same error
