Handle elasticsearch crashing on server

[aih]

• I already increased server to t3.medium, increased memory allocation to 2GB, prevented swapping

When running bill_similarity:

Finding Similiarity /opt/flatgov/FlatGov/server_py/flatgov/congress/data/115/bills/s/s1519/text-versions/pcs/document.xml
Could not process for similarity: ConnectionError(<urllib3.connection.HTTPConnection object at 0x7f85908aca60>: Failed to establish a new connection: [Errno 111] Connection refused) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x7f85908aca60>: Failed to establish a new connection: [Errno 111] Connection refused)

I now set the heap size in jvm.opt to 1500m (1500Mb), i.e. < 50% since not all of the 4GB of RAM on the server are available. I also set bootstrap.mlockall: true in the elastic.yml to prevent it from taking more memory or swap.

The solution above has worked to prevent crashes. Closing.
