Missing output data when run on Linux

[lpanger]

I have a suite of cypress tests, works fine on Windows machines but has issues when run on Linux (Ubuntu 20).

I'm using promises to start multiple cypress instances using the module API. At the end, I use Promises.all() to wait for them to all resolve. Some of them will return an error saying "Could not find Cypress test run results". It looks like the tmp file that cypress creates is empty.

For the promises that do not have test results, the chrome and Cypress processes are still up. I tried connecting to the chrome remote debugging port and there was no information displayed. See image below. The "test" link goes to a chrome dev tools view but shows nothing.

Has anyone else encountered this problem? Are there any tips on other things I can look at to try to debug the problem?
