Well, this is a weird and very specific issue, but it may help someone in search later. If you start seeing an error like

[ERROR] Completed: Test with Go - <target> - failed (exit code -9).

it may be your antivirus. I just had Crowdstrike’s ML agent decide that the pants test runner was malicious and start killing my processes. Super baffling one to debug because I didn’t make any code changes and all of a sudden tests were failing all over the place.

🥲

-9 means a process got killed with

SIGKILL

likely by the kernel out of memory killer
