Why does it consume so much memory? The memory is constantly maxed out. My server is configured with 8 cores and 16GB RAM, running 6 K8s nodes, and memory usage frequently exceeds 15GB. I've loaded about 10 models into it from the database. Are there any good solutions to this? The service restarts during peak hours. Although I've implemented graceful shutdown, making the restarts imperceptible to users, it's still an issue.
