OrientDB 2.1.9 crashes with OStorageException EOFException when running SQL script in console - orientdb

Question

I've been using my SQL database initialization script for a while, but it seems that recently the database crashes in the middle of the execution and I don't know why, but here's some details:
I am running OrientDB on Ubuntu 14 Trusty x64 (via Vagrant)
It always seems to crash while the script attempts to create a UNIQUE_HASH_INDEX, but doesn't always crash at the same UNIQUE_HASH_INDEX instruction
The script creates a lot of vertices and edges, but for example, it will crash here (see line with UNIQUE_HASH_INDEX):
CREATE CLASS Channel EXTENDS V;
CREATE PROPERTY Channel.version LONG;
CREATE PROPERTY Channel.channelId STRING;
CREATE INDEX Channel.uq_channelId ON Channel(channelId) UNIQUE_HASH_INDEX;
The database crashes entirely with the following error:
Creating index... Error:
com.orientechnologies.orient.core.exception.OStorageException: Error
on executing command: sql.create INDEX Channel.uq_channelId ON
Channel(channelId) UNIQUE_HASH_INDEX
Error: java.io.EOFException
Looking at the log files, the only hint I get are the last two lines:
2016-01-14 17:17:05:437 INFO Received signal: SIGTERM [OSignalHandler]
2016-01-14 17:17:05:454 INFO Received signal: SIGTERM [OSignalHandler]
How can I resolve this issue, or at least get better hints as to what is making the database crash?
I also test with OrientDB 2.1.6, as I was running the older version initially. Same problem.

Sorry, false alarm -- this is a Vagrant issue, not an OrientDB issue. Running the exact same script on a 32bit instance instead of 64bit solved my problem, and installing the same script on a real 64bit server also works.
