Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

v0.6.34

Ollama Version (if applicable)

0.7.1

Operating System

Ubuntu 24.04.3 LTS

Browser (if applicable)

Firefox 144.0

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

running 'open-webui serve' from the command line should produce a running instance of open webui (i'm running pip, not docker).

Actual Behavior

the system crashes and dumps the core with a mem alloc error. running fully-patched ubuntu 24..04.3 environment

Steps to Reproduce

  1. start with fully patched ubuntu install
  2. start venv
  3. run uv pip install --upgrade open-webui to upgrade from 0.6.33 to 0.6.34
  4. open-webui serve
  5. i get the log output shown below

Weird. I also run it on Ubuntu Server 24 LTS on pip and upgraded from 0.6.33 to 0.6.34 today on a test environment, and it worked perfectly fine - so I match exactly your description but no issues for me.

Do you have any other steps to reproduce?
Are you sure this is an issue of Open WebUI or other faulty packages?
Are there any relevant system level logs?

The crash happens right after Open WebUI loads the embedding model (sentence-transformers/all-MiniLM-L6-v2). I'm going to try forcing an update to sentence-transformers, and then trying to bypass embedding on startup. i'll also re-run with memory debugging. sentence-transformers is v5.1.1

  1. updating sentence transformers doesn't help
  2. bypassing embedding at startup doesn't help:
    export BYPASS_EMBEDDING_AND_RETRIEVAL=true
    open-webui serve

i'll post the output from valgrind next.

Are you running out of memory (RAM) when this occurs? Swap maybe? Which means disk space as well.

nothing else on my system has changed, just updating open webui to v0.6.34. reverting to 0.6.33 doesn't help, which makes me wonder if there's a corruption in one of the dependencies?

what do you make of this: mmap(NULL, 134946025295872, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM

to me it looks like it's trying to allocate lot of TB of RAM?

That's what it looks like, yeah... That's why I thought of RAM; the error relates to it. Could be a fluke though as well...

Does activity monitor show that the RAM is actually being consumed?
Or does it just stop at the attempt to allocate it?

No, it's not actually being consumed. I think I will try rolling back pytorch and then sentence-transformers to earlier version to see if one of those is the culprit

Can you try from a fresh installation of Open WebUI?
Careful not to lose stuff you might have saved and want to keep.

And if you have another PC, can you test it there as well?

Just to rule out the "works on my machine" theory...

Encountered the same error and solved by downgrading to torch 2.8

I figured out the root cause, and for me the latest torch release was the issue. I'm CPU-only, so I removed and replaced with:
torch 2.9.0+cpu
torchaudio 2.9.0+cpu
torchvision 0.24.0+cpu
