OOMKilled in InfluxDB, how to preperly set memory settings?

1

Hello,
Since I’ve migrated from Docker to Openshift, I have problem with OOMKilled in InfluxDB.
It looks like InfluxDB is killed everyday at the same time (there is cron tasks inside InfluxDB?).
I set up continous queries and retention policies for metrics but it didn’t help.
I set up memory settings (INFLUXDB_DATA_CACHE_MAX_MEMORY_SIZE, INFLUXDB_DATA_CACHE_SNAPSHOT_MEMORY_SIZE, INFLUXDB_DATA_CACHE_SNAPSHOT_WRITE_COLD_DURATION) to have control at memory usage, but it didn’t help too.
Do You know how to overcome this problem? Or maybe some advice what settings can I add to avoid OOMKilled in InfluxDB?

Best Regards,

We will need more info than this.

Can you post your logs?
How many writes per second are you doing?
How much memory does the VM have in total
Are you using TSI(instead of TSM). Tsi1 uses less memory
