Ok so I have built a pretty typical mob grinder. (4 8x8 spawning pads with a "+" shaped water funneling system three vertical floors of that config water only at the bottom.)

So as I said pretty typical, and functioning, I built a replica in creative with ideal everything. The thing churns 'em out like you would expect.

My question, I built this thing in my factions territory on the craftgasm server. At almost the sky limit. (To cut out the "underground caverns" kryptonite) and spits out mobs at a painfully slow pace. Like slower than what I would expect based off of the vanilla minecraft creative tests. (Even giving it a time handicap, the thing isn't working)

The testing led me to think it was bats. I go up to check, no bats even. I have checked my distance from the spawner, that's not it.

Maybe the server is doing something? Maybe it is set up to prevent hostile mobs from spawning in your territory? Not sure. I put it to you, kind users of the Internet. What are your thoughts?

spawning locations are checked at chunk level so height doesn't matter at that point, also mobs might be spawning in caverns loaded by other players and not despawning there – ratchet freak Jun 6 '13 at 20:26
Pretty sure that wouldn't be it. As my grinder is beyond 128 blocks from sea level. And there aren't really any other places around that could have caverns. So unless they are there in the cavern (player not mob)they would despawn. – Bob Jun 6 '13 at 22:31
Height actually decreases mob spawning. – SevenSidedDie Jun 6 '13 at 23:25
Oh? How do you mean. I haven't really seen that. – Bob Jun 6 '13 at 23:38
Are you alone on the server? I am not familiar with those mods, but vanilla spawning algorithm does not try to spawn each player's allotment of mobs exactly around this player. I.e. if one player goes to sea or the sky, his portion of mobs are essentially dumped on other people. The game spawns mobs wherever it is easier. – Orc JMR Jun 7 '13 at 2:28

It is probably not dark enough. Try closing off all entries to the spawners.

There are no spawners referenced in the question, they are using the normal mob spawning rules. – ChargingPun Jun 7 '13 at 14:47
What chargingpun said. This is a grinder, not a spawner trap. Would that I could obtain spawners. That would be suweeeeeeet. – Bob Jun 7 '13 at 19:19

Well, I guess I'm going just chalk this one up to lag. Between someone's suggestion on here, and low mob encounters in general on that server... Thanks to all that tryed to figure this one out with me.

You should accept this answer if you consider this matter to be resolved. – kotekzot Apr 26 '14 at 23:38

The Minecraft entity limit is based on chunks, not quasi-chunks. You need to light up practically every dark area on the ground AND in caves in the surrounding chunks to have it work like you're saying.
