dockerized Jenkins is crashing when running jest unit test

I have a few npm projects that use JestJS for unit testing.

For some reason, the command npm run test make crash and restart my (official) Jenkins container.

I have checked the log stderr and stdout and I don't see any trace of errors.

• How can I upgrade the log level of Jenkins ?
• What would make Jenkins crash without any warning ?
  • jdk ?
  • node version ?
  • ram/cpu ?
