Server watchdog timeout — why your Minecraft server crashes

Example error line

[FATAL]: A single server tick took 60.00 seconds. Attempting to keep server alive!

Cause

A single server tick took far too long, so the watchdog killed the server — usually caused by memory pressure or one very heavy plugin/mod.

Fix

Find the heavy plugin/mod. If this keeps happening under load, more RAM usually helps (see the RAM Calculator).
