Intermittent compilation errors :read_cache :infinity when running tests in GitHub Actions

We keep hitting the following intermittent error when running tests in GitHub Actions:

== Compilation error in file test/ctl/set_operator_policy_command_test.exs ==
** (exit) exited in:<34162.3242.0>, {:read_cache, -576460752303381870}, :infinity)

This happens in both OTP v21.3 & v22.3 and we cannot reproduce it reliably:

Has anyone else seen this before? I couldn’t find any GitHub issue or post on this forum that mentions this error.

In the meantime, I’m running the tests twice, because maybe second time lucky :thinking:
