Bug Report

Installation Method

Docker

Environment

Open WebUI Version: 0.5.16
Ollama (if applicable):
Operating System: AWS Fargate ECS Task
Browser (if applicable): Chrome 133

Confirmation:

I have read and followed all the instructions provided in the README.md.
I am on 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 the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

I expect to be able to chat using the Function that makes a call to OpenAI Assistants API

Actual Behavior:

The ECS container crashes upon asking a question with this error - "[engine] caught signal [SIGTERM]" and it restarts and all users lose their session.

Description

Bug Summary:
Got OpenWebUI working locally as a docker container which talks to an OpenAI assistant via a Function - https://openwebui.com/f/mantonherre/assistant_openai.
While replicating this for wider use in our internal prod environment as AWS Fargate ECS Tasks/container, noticed that the container crashes often when this specific assistant that calls the Function is enabled and a question is sent in the chat. The debug logs have no useful information. All I see is "[engine] caught signal [SIGTERM]" in the container logs from ECS

Reproduction Details

Steps to Reproduce:
Create a Function from the link posted above. The model using this Function should be auto enabled. On the chat prompt, select this model and ask a question. The response will never return and if your refresh the browser, it will keep spinning. The Cloudwatch event logs for ECS will show that the container died and restarted. [engine] caught signal [SIGTERM] is the only line indicating the shutdown.
The healthchecks are supposed to run every 30s and 5 times.

Logs and Screenshots

[engine] caught signal [SIGTERM]

Browser Console Logs:
