you just got an FatalProcessOutOfMemory. So you ran out of memory and thats why the service is crashed. Give it more memory or optimise your app for more efficiency.

Both works, but efficiency is nearly always better. Increasing memory however is faster

okay

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

... out of memory

same again. Either increase memory or optimise your app
