Hanging check

[Noki]

Describe the bug

I have multiple checks setup, and only one fetch_worker due to limited ressources on my NAS. The worker got stuck, so all my checks stopped working:

Version
v0.45.23

To Reproduce
No idea how it happened but the check uses the Playwright Chromium/Javascript

Expected behavior
I would expect the following:

• The check that got stuck should fail with a timeout. There should be the option to set the timeout globally and for specific checks.
• There should be a notification for checks that failed with a timeout
• There should be a notification for checks that could not be run within their usual schedule, so the admin could take actions

heya, no logs from the container? platform? docker? pypi install? downloaded directly?

[Noki]

The relevant part of the docker log (bottom to top):

Looks like it was detected that the browser steps were incomplete. After that it hang. The other containers did not output any useful log at that time. Hope this helps.

Looks like it was detected that the browser steps were incomplete.

No its just saying its using a different driver, its just a debug message really

After that it hang.

The logs only show to step 4 (press enter)

any more info?

what about proxies? or external browsers? you didnt say

[Noki]

Step 4 is the last step before evaluation. It submits a form, than the check should take place on the result displayed. I configured a 10 second wait time before extracting the text:

I don't use proxies / external browsers. Here is my docker compose file:

version: '3.2'
services:
    changedetection:
      image: ghcr.io/dgtlmoon/changedetection.io:latest
      container_name: changedetection
      hostname: changedetection
      volumes:
        - /volume1/docker/changedetection/datastore:/datastore

      environment:
        - PLAYWRIGHT_DRIVER_URL=ws://playwright-chrome:3000
        - HIDE_REFERER=true
        - FETCH_WORKERS=1

      ports:
        - 3003:5000
      restart: unless-stopped

      depends_on:
        playwright-chrome:
          condition: service_started

    playwright-chrome:
        hostname: playwright-chrome
        image: dgtlmoon/sockpuppetbrowser:latest
        cap_add:
            - SYS_ADMIN
        restart: unless-stopped
        environment:
            - SCREEN_WIDTH=1920
            - SCREEN_HEIGHT=1080
            - SCREEN_DEPTH=16
            - MAX_CONCURRENT_CHROME_PROCESSES=2

is it reproducable?

[Noki]

No. Works again after I restarted all containers, therefore some detection would be nice since no checks ran over the weekend due to missing alerting.

I am hitting this too over at #1836 (comment). Also maybe related: #2293

Running v0.45.23 on a Synology NAS. What kind of logs would be helpful here, if any?
