Failed to build Docker image aws_beanstalk/staging-app:  tar writer: io: read/write on closed pipe" 
Error response from daemon: Untar error on re-exec cmd: fork/exec /proc/self/exe: cannot allocate memory. Check snapshot logs for details. (Executor::NonZeroExitStatus)

I have a Pickle object in django_app/content_classifer object. There is a class to predict the result and it's initializing itself when celery tasks file gets initialised.

docker build keeps failing after giving an error message as in the title.

I had same issue few minutes ago, when I found your issue :) I had some files opened = they were used by another application(GIT)

Please make sure that no files are being used.

Hope it will help.
