warning

The tick loop fell 1025ms behind, 1025 ticks in one go

A tick took far longer than the 50ms it is allowed, so the server ran behind real time and skipped ahead to catch up (once in this log). Players see rubber-banding, delayed block breaks and mobs that stutter. One burst after a restart, a world upgrade or a chunk pre-generation run is normal. A steady stream is lag with a cause: profile it with spark ("spark profiler --timeout 120" in the console) rather than guessing. The usual culprits are view-distance and simulation-distance set too high, entity or item build-ups, chunks generating live as players explore, and garbage collection pauses when the heap is too small.

info

MOTD: 'A Minecraft Server'. Technically true. Memorably not.

Set motd in server.properties. Anything you would say out loud works better than the default.

info

sync-chunk-writes=true. Every chunk save politely queues behind the disk.

Set sync-chunk-writes=false on vanilla, Forge and Fabric servers for a real performance gain on chunk saving. Paper already handles this for you.

info

spawn-protection=16: the classic invisible wall. No log line, just confusion.

Non-op players silently cannot place or break blocks within 16 blocks of spawn. Set spawn-protection=0 unless you want that, and op at least one admin.
