Bug Report

Description

Bug Summary:
I am starting both containers, ollama and ollama-webui, with docker compose. This works well but with each interaction it slows down. I analyzed the usage statistics of the containers and recognized that the ollama container does not clean its memory usage. So the memory getting blocked more and more with each interaction.
After restarting the container the memory is cleaned up.

Steps to Reproduce:

  • start the containers with the docker-compose.yaml
  • register/login
  • pull a model (use a larger one, like mixtral, to see the described effect better)
  • start some chat sessions
  • monitor the memory usage with Docker Dashboard or with "docker stats --all" or "docker stats ollama"

Expected Behavior:
After ollama responded to a question, the memory cleans up automatically.

Actual Behavior:
After ollama responded to a question, the memory keeps reserved/used.

Environment

  • Operating System: Host: macOS Sonoma 14.2.1 (MacBook Pro M1, ARM), Docker Container: Ubuntu 22.04.3 LTS
  • Browser (if applicable): Chrome 121.0.6167.85

Confirmation:

Out of scope for this project. This is related to caching the model files in memory for some time after loading them. The behaviour is tunable, but again, out of scope for this project, please refer to Ollama.
