Playwright tests running in self hosted GitHub Actions runner using Azure VM crashes during tests

I have for weeks now used the GitHub -hosted GitHub actions runner, but since my Playwright tests can take up to an hour to complete, i have started trying out self-hosted GitHub actions runner using a free tier VM from Microsoft Azure to save on the 3000 free minutes of GitHub actions time i get per month…

After running 3 tests out of 273 tests, the VM crashes after running at 100% CPU for a while (see screenshot).

My current playwright.config.ts results in 1 worker.

Has anyone else experience with this issue?

import { defineConfig } from '@playwright/test';
import * as path from 'path';

export default defineConfig({
    testDir: './tests',
    fullyParallel: false,
    forbidOnly: !!process.env.CI,
    retries: 3,
    workers: '50%',
    use: {
        navigationTimeout: 30000,
        actionTimeout: 15000,
        viewport: { width: 1280, height: 720 },
        trace: 'off',
        browserName: 'chromium',
        launchOptions: {
            args: ['--no-sandbox', '--disable-setuid-sandbox']
        }
    },
    reporter: [
        ['html', { outputFolder: path.resolve(__dirname, 'playwright-report'), open: 'never' }],
        ['list']
    ],
    timeout: 120000
});
