Monerod sync crashes my Ubuntu server

basedtrader_dev

I am running a server with btcpay following this guide: https://sethforprivacy.com/guides/accepting-monero-via-btcpay-server/

However the docker process Monerod keeps killing my server. When I restart the server the monerod process is unable to start again (this has happened twice before, I deleted the monero database, it begins to sync again then errors out and kills my server like this):

I am pretty stumped at this point and would appreciate any advice.
