Ovnkube-node container max memory usage was 110 MiB with 4.14.0-0.nightly-2023-05-18-231932 image and now it is 530 MiB with 4.14.0-0.nightly-2023-07-31-181848 image, for the same test (cluster-density-v2 with 800 iterations, churn=false) on 120 node environment. We observed the same pattern in the OVN-IC environment as well.
Note: As churn is false, we are calculating memory usage for only resource creation.

As the test was successfully run in the CI, we couldn't collect a must-gather. I can provide must-gather and pprof data if needed.
We observed 100 MiB to 550 MiB increase in OVN-IC between 4.14.0-0.nightly-2023-06-12-141936 and 4.14.0-0.nightly-2023-07-30-191504 versions.
