but the server was only using 400 meg of RAM
When you say "the server" was only using 400 meg, that's very vague. As I said to someone before, Java memory stuff isn't as straightforward as that.
:(
Did you launch the gave with any min/max memory settings?
(Possibly it defaults to 512MB max, so when it gets to 400MB it starts trying to do garbage collection, but can't do it quickly enough, and thus everything slows down).
If not, try launching it with this:
code:
java -Xmx1G -Xms1G -jar minecraft_server.jar
Which is giving it a maximum amount of 1GB and telling it to go ahead and allocate the whole 1GB.
