In MTA 8.0.0 we need to add a release note that concurrent usage of the Solution Server may lead to idle connections not being freed. 

Example of an error:

asyncpg.exceptions.TooManyConnectionsError: sorry, too many clients already
[09/29/25 09:39:25] ERROR    Error calling tool 'create_incident': sorry, too many clients already                                                                                   tool_manager.py:140

Manual Workaround to set an idle connection timeout:

oc -n <mta namespace> exec deploy/kai-db – psql -U postgres -d postgres -c "ALTER ROLE kai SET idle_session_timeout = '1min'; ALTER ROLE kai SET idle_in_transaction_session_timeout = '1min';"
