Chunks not unloading. Running out of memory.

Chunks are not unloading, and memory used steadily increases. 50,000 chunks loaded right now.

Is Bukkit supposed to unload chunks without players by default?

This server is running CraftBukkit version git-Bukkit-1.2.5-R5.0-39-ga2db865-b2309jnks (MC: 1.3.1) (Implementing API version 1.3.1-R0.1-SNAPSHOT)

 

are you saying that your minecraft client is running 1.2.5 but the server is 1.3.1?

 

No. I just copied and pasted version from console.

 

?

did you update your minecraft game?
and are you using the newest bukkit dev build?

 

is this on a normal world or is it on a flatmap or custom generator. i have been having issues with custom generated worlds not sending chunks properly.

 

Dude, it says exactly what version I am using. You type "version" in console to get that. Why are you asking what version I am using when I provided that? You have asked twice now. Geez.
