While running, mocha tests are failing at some point with the following error:

# Fatal error in , line 0
# Fatal process out of memory: Zone
#FailureMessage Object: 0000000E08BF9C50

Repro steps

See this workflow run: https://github.com/waldekmastykarz/cli-githubactions/runs/1844914810?check_suite_focus=true
In the same repo you can find previous runs where I tried adjusting different Node settings without any result. I also tried to run the same tests on a Standard DS2 v2 Azure VM with Win 2019 and there the code runs as expected.

The same tests work just fine on the Ubuntu and macOS agents.

Hello, @waldekmastykarz
Could you please try to increase swap at runtime?

- name: configure Pagefile
  uses: al-cheb/configure-pagefile-action@v1.2
  with:
      minimum-size: 16GB
      maximum-size: 16GB
      disk-root: "C:"

Thank you for the tip! Will give it a try and let you know if it helped 👍

[waldekmastykarz]

Works like a charm! Does this mean this is the recommended way forward?

Does this mean this is the recommended way forward?

Yep, currently we don't have any plans to change a vm size or the default settings for a pagefile.
