디비 사용량 초과 에러가 뜬 경우, 해결방법은 사용가능한 크기를 늘려주면 된다.

nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::chain_plugin --plugin eosio::chain_api_plugin --plugin eosio::http_plugin --plugin eosio::history_plugin --plugin eosio::history_api_plugin --data-dir CONTRACTS_DIR/eosio/data --config-dir CONTRACTS_DIR/eosio/config --access-control-allow-origin='*' --contracts-console --http-validate-host=false --verbose-http-errors --filter-on='*' --http-server-address=0.0.0.0:8888 --http-alias=fabius.ciceron.xyz:8888  --chain-state-db-size-mb=3072 >> nodeos.log 2>&1 &

nodeos를 실행할 때, --chain-state-db-size-mb=3072 를 추가해서 사용 가능한 크기를 설정해준다.
