   Also ran into this issue:
   
   ```
   { error: 'unknown_error',
     reason: 'badarg',
     ref: 4258677272,
     name: 'unknown_error',
     status: 500,

   Looking at the DB logs around that time:

   The strange thing is that this seems sporadic: trying to reproduce it with a smaller bulk POST always succeeded, and now even the larger bulk POST (with prod data) seems to work.
   
   Will update this issue if I learn more.
   
   Running the official Docker image of 2.1.1 on AWS EC2, if it helps.
