Guarantee issues coming randomly

[fallais]

Hello,

We are running RethinkDB with Docker, everything worked well since a few days and now the container is crashing randomly because of "guarantee" issues.
Once it is crashed, the container never restart again, like if the database is corrupted.
We need to restore a previous snapshot.
And it is crashing again a few days later.

Here are the logs.
