ECONNRESET crashes app after aborted connection

[MR4online]

Hi there,

As far as I understand, MariaDB closes the connection after some time.
MariaDB Log:
2025-10-10 2:03:44 5 [Warning] Aborted connection 5 to db: 'xxx' user: 'root' host: '172.19.0.16' (Got timeout reading communication packets)

Then my Service (NodeJs 24 in a docker container) crashes:

[2025-10-10 02:03:44] ERROR: 	SQL read ECONNRESET : [
  Error: read ECONNRESET

  }

}

Node.js v24.9.0
[nodemon] app crashed - waiting for file changes before starting...

I wonder why, because:
I create the connection inside a try-catch call:

    private async getDbConnection(): Promise<mariadb.Connection> {
        try {
            if (!this.db) {
                this.db = await mariadb.createConnection({
                    host: process.env.MARIADB_HOST,
                    user: process.env.MARIADB_USER,
                    password: process.env.MARIADB_PASSWORD,
                    logParam: true,
                    logger: {
                        query: (msg: string) => {
                            Logger.debug('MariaDB Error - query:', msg);
                        },
                        warning: (msg: string) => {
                            Logger.warn('MariaDB Error - warning:', msg);
                        },
                        error: (err: Error) => {
                            Logger.error('MariaDB Error - error:', err);
                        },
                    },
                    database: process.env.MARIADB_SCHEMA,
                    initSql: `CREATE DATABASE IF NOT EXISTS \`${process.env.MARIADB_SCHEMA}\``,
                });
            }
            return this.db;
        } catch (e) {
            Logger.error('getDbConnection()', e);
            throw new Error('DB Connection failed');
        }
    }

Do I have to use Connection-Pools even for simple, long-running services?
Or, how do I catch these Error and reconnect, when the error doesn't get catched?

Thank you very much!
