here is the graph from out NMS about memory usage
and I would say we have spikes, but they are not every 24h but rather every 30
minutes and I guess it's because of our CQ we use for downsampling. I can post
that CQ if that can help.
We are aware of cardinality when we designed our solution and currently we have
81761 series which I guess it's quite ok for this amount of RAM.

Yes, we always have successful writes and we have 204 response returned by
InfluxDB. By missing the whole measurement I mean that for example we have one
measurement at 10:00 pm in InfluxDB and in our file (we do write data in file
for debugging), then we have next measurement in 10:05 pm in both InfluxDB and
file, the next measurement in 10:10 we are missing in InfluxDB but we do have
that measurement in file and still we have 204 response returned by InfluxDB.
