os error 1224 in Azure DevOps pipeline

[bbarrette-msft]

We're trying to integrate the use of swc/jest in our monorepo project (currently in a single package of the project to try things out), and things work great locally after adding the use of swc_mut_cjs_exports to get things running for us.

Sometimes (as in, not every time, and not on the same file all the time), it fails when running in the Azure DevOps pipelines. Can't provide a minimal repro unfortunately since it's not constant, but this is the error message we're getting when it fails (see below). Not sure if this is actually an issue in swc or a configuration that we might not have set that creates those errors, so mainly looking for guidance if you would know what could be the root cause.

Thanks in advance!

The error:

The requested operation cannot be performed on a file with a user-mapped section open. (os error 1224)

It cannot be debugged without a reproduction

[bbarrette-msft]

I know, but with it being intermittent and not on the same files, I didn't find a way to have something constantly reproducible. Was mainly looking for thoughts if this is something someone might've seen before based on the error message and stack.
What I did find since is that running the tests with the runInBand flag completely gets rid of the issue
