This error plagues server admins using Pufferfish, the high-performance fork of PaperMC. But don't worry! ⚠️ This guide cuts through the chaos with precise, actionable steps to squash those spiky signals and get your world spinning smoothly again.
We'll dive deep into what triggers this error, why it happens, and how to fix it permanently. Stick around – by the end, your server will feel brand new. Ready? Let's dive in! 🚀
Pufferfish is a battle-tested optimizer for Minecraft servers, boosting TPS (ticks per second) and reducing lag. The Spiky Signals error is Pufferfish's way of flagging performance spikes – sudden bursts of high CPU or memory usage that cause rubber-banding, entity lag, or full crashes.
Typically logged as:
[Pufferfish] WARNING: Spiky Signals detected! Possible causes: High entity counts, chunk loading issues, or plugin conflicts.
This isn't a "crash" per se, but untreated, it leads to plummeting TPS (below 20) and frustrated players. Recent reports from the Pufferfish Discord show it's spiking in 1.20.6+ versions due to new world gen and mob AI changes.
Pinpointing the culprit is half the battle. Here's a breakdown:
Pro Tip: Check your latest.log for patterns – spikes often cluster around player joins or redstone ticks. 👀
