My console is spamming messages — is it harmful and how do I stop it?
Repeated console spam is usually a symptom rather than a danger in itself — a misconfigured plugin or mod, or an error loop. It's rarely harmful on its own, but it can hide real problems and waste resources, so it's worth tracking down.
Why this happens
A line that repeats over and over is your server telling you something is wrong on a loop: a plugin failing to load, a mod erroring, a missing file, or a bad config value. Reading that line is the fastest route to the cause.
How to stop it
- Read the repeating line — it names the culprit (a plugin, mod, missing file, or config value).
- Use "Copy all console output" (or Share logs via mclo.gs) so you can read the full message without the flicker.
- Fix the source: correct the config, update or remove the offending plugin/mod, or add the missing file.
- Restart and confirm the spam has stopped.
Warning: Constant error spam often precedes a crash or performance drop — don't ignore it, especially if it mentions memory, chunks, or a failing task.
Tips & best practices
- Change one thing at a time and restart, so you know exactly which fix worked.
Frequently asked questions
Is console spam dangerous by itself? Not usually, but the underlying cause can be — a crash loop or memory error behind the spam is the real risk.
I can't identify the plugin causing it — help? Share the log via mclo.gs using the Console button and ask in Discord; a full log link makes it far easier to spot the culprit.
