Memory leak in stac-fastapi-pgstac:6.1.1 deployed on RKE2 — container memory usage grows until nodes are exhausted

[JavierPelegrin]

I am running stac-fastapi-pgstac:6.1.1 on an RKE2 Kubernetes cluster and am experiencing a severe memory leak. After deployment, the STAC API container’s memory consumption continuously increases over time until it eventually consumes all available memory on the cluster. The process is not releasing memory, and the pod does not crash or restart — it just keeps growing until the node is out of memory.

I don't have a lot of information, that's why I started a discussion and not a new issue; I wanted to know if anyone might have an idea or has experienced a similar problem deploying a PGTAC.
