cypress crash during long test run with error thrown by plugin / IPC channel closed

See original GitHub issue

Current behavior:

After updating to 3.0.1 (from 3.0.0), after running a fairly large test run of 50 specs (compiled with the ts plugin), I’ve started to encounter these errors about 2/3 of the way through the suite. Every test afterwards fails immediately with the below stack trace:

Error: The following error was thrown by a plugin. We've stopped running your tests because a plugin crashed.

Error [ERR_IPC_CHANNEL_CLOSED]: channel closed

Desired behavior:

Steps to reproduce:

I’m not sure if it’s specific to my suite – I’ve tried on a repo of simple tests (in the 50 or some odd range), but I think it has more to do with the size or complexity of the tests. I’ll have to do some work to get an example of the crash.
