Another 11 minutes of play:

@Anthony Martin
Haha. My bad.
So, my /minecraftserver/data/ folder only has one file in it, villages.dat. It's 55 bytes in size.
EDIT: /minecraftserver/world/data/Mineshaft.dat is 19KB.

@Anthony Martin My world folder, imported from previous versions, is 97MB. My region folder is around 80MB. My entire server folder is under 200MB. Want the whole thing? 😛

Hello gents,
I woke up this morning to find the following in my server's terminal:

[00:03:33] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 6478248ms behind, skipping 129564 tick(s)
[00:42:37] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 2293780ms behind, skipping 45875 tick(s)

[09:02:31] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 3829528ms behind, skipping 76590 tick(s)

The load was currently hovering at around 35% of 1 core, which seems high for a server to idle at with no one logged in and playing, but at the same time low for me to be seeing Server unavailable in the Multiplayer pane. Seems there is in fact something uncontrollably spiking CPU usage after all, even when the server is empty.

EDIT: Attaching some logs.
EDIT 2: Just kicked off while connecting directly within my own network (10.0.1.5). Same CPU behavior...

I get this without fail within a few minutes of play. I just recently upgraded from much older world data (1.5.x). I'm finding 1.7.2 completely unplayable. Have I missed something perhaps in upgrading my server? :\

Just happened to me. Was just walking and was kicked off. Terminal log was hung. I entered Stop + Return and after a solid 30 seconds I found the following:

Running on a 8GB ram Mac Mini (Core 2 duo). Only 1 player on the server, me, and top reported a minuscule amount of CPU usage... so not sure what's going on. Need anything else? 🙂

Thanks!
