   Hi, I noticed something similar, we just upgraded a couple hours ago.
   Even with pgbouncer in front of the postgres db, api will fail after a 
certain time.
   We have 2 api and 2 scheduler, 1 triggerer, 3 workers.
   ```
   core:
           parallelism: 128
           max_active_tasks_per_dag: 64
         scheduler:
           max_tis_per_query: 256
         database:
           sql_alchemy_pool_size: 5
           sql_alchemy_max_overflow: 10
           sql_alchemy_pool_recycle: 600
   ```
   pgbouncer set at
   ```
   parameters:
         max_client_conn: "1000"
         default_pool_size: "30"
         min_pool_size: "10"
         reserve_pool_size: "10"
   ```
