Out of memory error: Killed process 501

Just installed InfluxDB on an AWS eC2 instance (t2.micro to begin with) for a home automation setup. The t2.micro has 1GB of RAM and 30GB of storage.

Installation was reasonably straight forward and I now successfully can push data into InfluxDB.

Was on the console recently to check up on things and got this error.

Out of memory: Killed process 501 (influxd) total-vm:1513848kB, anon-rss:787504kB, file-rss:0kB, shmem-rss:0kB, UID:113 pgtables:1872kB oom_score_adj:0

Where can I find info on what this exactly means (other than it killed the service) and how to configure InfluxDB in line with the resources available on my instance (i.e. limited)?
