DBT run returned non-zero exit status 137 in Version 0.18 while running through Airflow Dag

I get the following error while trying to run a simple DBT model from Airflow Dag. Where as the same runs faster from my local. I am on BDT version 0.18. Any insights into this error? Looks like there is a memory leak happenig here while running.

Command ‘dbt run --profiles-dir /usr/local/airflow/tmp/profile/remote-learning-dev-dev-hash --model GOOGLE_MEET’ returned non-zero exit status 137.
