cap_import
What happened
A run has a limit on the time to load. When the script goes over, the sandbox stops it and the run ends with this code. detail names the cap (import_ms), how much was used and how much was allowed. The caps for a run are in the code sandbox section of the Limits page.
What to do
Look at what your file does while it is being loaded, outside any function, and keep that short. Three load timeouts in a row pause your code runs: see devcode_import_cooldown.
