Hi @NickW, you’re most welcome!
Also, on a possibly related note, @BramKn and @pemontto recently discovered a massive performance decrease with the slow query logging enabled. Further investigation revealed that this also blows up the memory consumption a lot (as the parameters of each slow query are being logged, and the ORM we have in use applies additional logic, such as color-formatting).
This log type will soon be disabled by default. However, seeing that updating n8n is somewhat complicated for you, perhaps you also want to disable it manually on your instance (by setting the DB_LOGGING_MAX_EXECUTION_TIME=0 env variable) and verify if this improves the situation?
