Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

0.8.5

Ollama Version (if applicable)

0.17.5

Operating System

windows 11

Browser (if applicable)

edge 145.0.3800.70

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

not to crash, due to plenty of available system resources. Only 20% VRAM used and 80GB system RAM available.

Actual Behavior

crashes web app and openwebui process.

When I use any model, and provide it with that knowledge, ask it a question, it thinks for a while, I can see the powershell filling up, until eventually the powershell stops generating new lines, the web app becomes unresponsive, and I have to end openwebui in the task manager.

model remains in memory until ollama exited manually.

Only affects this particular knowledge.

Steps to Reproduce

  1. create a new knowledge item (all documents settings are default in the settings panel)
  2. download blender api from https://docs.blender.org/api/current/blender_python_reference_5_0.zip
  3. add the unzipped html api to the knowedge as the folder containing the unzipped api
  4. clicking save when it finishes ingesting.
  5. open a chat with any model
  6. click the + icon to attach that knowledge
  7. ask it anything.

It takes ages to generate the knowledge, so I've exported it and uploaded to dropbox here (too large to attach here 28.6mb) :

actually, I've just realised the problem is that the actual data isn't in the html files it's dynamically populated from .doctree files. I'll try rebuilding to plain text and ommit the html entirely. If it still has issues I'll re-open.
