I am installing airflow 2.4.3 on GCP. The pod airflow flower keep getting restarted.
Below is the snapshot of the logs:-

Although I have moved sql_alchemy_pool_size to [database] and base_log_folder to [logging] I am still getting these warnings in airflow flower logs.
Please help me with finding the root cause of this pod restart, and how I can prevent this.
Let me know if any further logs/info ( config ) is required.
This was due to low resources, after setting the CPU to 500m and memory to 512m, the pod is working fine.
