dervish54 opened a new issue, #30286: URL: https://github.com/apache/superset/issues/30286
### Bug description I guess the following issues are related to each other: 1. Superset regularly crashes with the `error: sqlalchemy.exc.TimeoutError: QueuePool limit of size 5 overflow 10 reached, connection timed out, timeout 30.00`. 2. Database Locks are accumulating in the Superset database. Here is an example: ``` Current locks: 124 waitstart, locktype, relation::regclass, mode, objsubid, granted (None, 'relation', 'pg_stat_activity', 'AccessShareLock', None, True) (None, 'relation', 'pg_locks', 'AccessShareLock', None, True) (None, 'virtualxid', None, 'ExclusiveLock', None, True) (None, 'relation', 'ab_user', 'AccessShareLock', None, True) (None, 'relation', 'ab_view_menu_name_key', 'AccessShareLock', None, True) (None, 'relation', 'ab_view_menu_pkey', 'AccessShareLock', None, True) <...> ``` 3. Importing charts and dashboards does not work When trying to import charts and dashboards to a new Superset server with the same configuration (except for the password and secret key), I get an error. 4. The version in the Settings dropdown is shown as "Version: 0.0.0-dev". I am sure this should not be the case. ### How to reproduce the bug 1. `git clone --depth=1 https://github.com/apache/superset.git` 2. `cd superset` 3. make changes to docker/.env: `POSTGRES_PASSWORD`, `DATABASE_PASSWORD`, `SUPERSET_LOAD_EXAMPLES=no` and `SUPERSET_SECRET_KEY` 4. docker compose -f docker-compose-non-dev.yml up -d 5. Login and face problems from the list above. ### Screenshots/recordings   ### Superset version master / latest-dev ### Python version 3.9 ### Node version 16 ### Browser Chrome ### Additional context ``` superset_app | File "/usr/local/lib/python3.10/site-packages/sqlalchemy/pool/base.py", line 894, in _checkout superset_app | fairy = _ConnectionRecord.checkout(pool) superset_app | File "/usr/local/lib/python3.10/site-packages/sqlalchemy/pool/base.py", line 493, in checkout superset_app | rec = pool._do_get() superset_app | File "/usr/local/lib/python3.10/site-packages/sqlalchemy/pool/impl.py", line 134, in _do_get superset_app | raise exc.TimeoutError( superset_app | sqlalchemy.exc.TimeoutError: QueuePool limit of size 5 overflow 10 reached, connection timed out, timeout 30.00 (Background on this error at: https://sqlalche.me/e/14/3o7r) superset_app | 2024-09-10 13:04:48,939:ERROR:superset.views.error_handling:QueuePool limit of size 5 overflow 10 reached, connection timed out, timeout 30.00 (Background on this error at: https://sqlalche.me/e/14/3o7r) superset_app | Traceback (most recent call last): superset_app | File "/usr/local/lib/python3.10/site-packages/flask/app.py", line 1484, in full_dispatch_request ``` ### Checklist - [X] I have searched Superset docs and Slack and didn't find a solution to my problem. - [X] I have searched the GitHub issue tracker and didn't find a similar bug report. - [X] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
