I’ve got a build that’s hitting the 1 hour time limit on the open source cloud instance but I only have guesses as to why it’s running slowly:

- It’s actually that big (testing on another VM to work this out)

- Running out of RAM and swapping

- IO issues because I’m running with many threads (will try new builds later with less threads)

How would I go about troubleshooting this? The process is just killed at the 1 hour limit with no info. AppVeyor allows you to remote into the running job, but I understand that’s a pretty special case.

Thanks,  
Adam
