How can you prevent a crash loop when automatically restarting workers in a Node.js cluster?
ARestart workers immediately without delay on every crash
BLimit the number of restarts within a time frame before exiting
CIgnore the exit code and always restart workers
DUse worker.disconnect() instead of cluster.fork()
Step-by-Step Solution
Solution:

  1. Step 1: Understand crash loops

    Rapid restarts on repeated crashes cause crash loops, harming stability.

  2. Step 2: Implement restart limits

    Limiting restarts within a time frame prevents infinite crash loops and allows recovery.

  3. Final Answer:

    Limit the number of restarts within a time frame before exiting -> Option B

  4. Quick Check:

    Prevent crash loops by limiting restarts [OK]
Quick Trick: Limit restart frequency to avoid crash loops [OK]
Common Mistakes:
  • Restarting immediately without limits
  • Ignoring exit codes
  • Using disconnect instead of fork incorrectly
