Problem
EC2 memory monitoring was previously relying on an unofficial 3rd party solution, which at one point was working intermittently.
The problem has become more pressing since PR #555 was merged, which reported a 19 MB increase in memory usage for a single bulk download of 10,000 submissions.
Solution
Upgrade to use an official solution provided by AWS here, which provides both memory and disk monitoring. The only change made was to the cron expression, which has been updated to report every minute instead of every 5 minutes.
The requisite permissions have been granted to our Elastic Beanstalk instance profiles.
