Log is deleted, because influx was falling after restart so we restarted machine and jurnaling was not set to persistent (after restart was journalctl deleted). Now is set to persistent, so I can post something on next monday … .

OOM is not reason (graph 1) because memory is raising after influx is not responding (500 node-fetch /api/v2/write is raising up and 204 write is falling down), so data are stocked in queue in NodeRed (last 2 graphs). Problem starts every monday around 2:05 am UTC+2
