OMMkiller terminated backup process

[emelianrus]

I'm trying use cron job to copy files from kubernetes to S3 and in kubernetes and got pod error OMMKilled
Looks like it slowly increase virtual memory and reaching pod limits.

Container limits set to: cpu 3. Memory: 5Gb
amount of copy files: 3401311
changing buffer memory didn't help
Am i doing something wrong?
or its memory leak issue?

I am having the same issue.
I increased the pod limits and requests and the problem was addressed.
The issue is that the memory consumption by the backup pod keeps rising during the copy process.
For a vanilla jenkins installation it reached ~2G.
I think this is unusable for large jenkins installations (or large backups in general)
