What is the size of the complete file? The bulk interface is designed to allow you to send multiple (not necessarily all) documents in a single request. It is typically recommended to keep the size of each bulk request below 5MB in size.

It's probably a good idea to work this out before you need it again. The log is the first place to look when things go wrong. By default Elasticsearch logs most things to `stdout`, and I think the default for the Docker image is to also log to `/usr/share/elasticsearch/logs` which you can bind-mount to somewhere persistent.
