Hostile monster spawn rate

[Yannis_Ofzo]

Earlier today I made a Dark room mob spawner for the drops, now once in a while I get a mob to fall, using the guide I followe I made the exact same room in my SSP and it rained mobs, so it's not as if my design is wrong. might be bukkit related, I hope it's fixable anyway >.<

How come your building a dark room spawner anyway? you have so many actual spawners

If this is indeed a bug, it is a bukkit bug. Nothing we can do about it.
