In my server.properties, I have game mode set to 0 (survival), spawn rates set to defaults (1 tick for mobs, 400 ticks for animals) difficulty set to normal and we are harldy seeing any mobs or friendlies.
We even have a mob-grinder which is failing to spawn more than 1 mob per-day.
This is running on craft-bukkit 1.2.5
Our host seems to think that others have reported the same sort of issue. Does anyone have any ideas what the underlying issue may be?
