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
