After one week the server still runs. The memory consumption is slightly higher than with 1.4.2 but it is stable and the last 7 days it did not exceed 600MB.

I'm still testing and watching my server. Right now it looks like memory usage is increased in 1.4.4 compared to 1.4.2 but it doesn't look like there's something leaking. I'll keep an eye on my server and will update next weekend.

I'm running the minecraft server for two players max on FreeBSD 9.1 with 4GB RAM. I tried several JVM: diablo 1.6.0, sun jdk 1.6.0, openjdk7, all compiled from the ports system. The server is currently running with jdk1.6.0 using

JAVA_HOME=/usr/local/jdk1.6.0 java -Djava.security.egd=file:/dev/random -Xmx2048M -Xms512M -jar minecraft_server.jar nogui

Before Minecraft 1.4.2 I used weekly snapshots and every 3-4 days the server would crash with an out of memory exception. This bug was finally fixed with 1.4.2 and once I updated the server to 1.4.2 it ran without a single restart for 3 weeks. With 1.4.2 the server would consume ~150-200MB RAM while no one is logged in. Since yesterday I'm running 1.4.4 and the server is showing similar symptoms as it did with pre-1.4.2 versions: After a fresh start consuming at least 300MB RAM, when two people log in it jumps up and won't go below 500MB after they logged out. But I guess it's too soon to draw any conclusions.

I think I can confirm your assumption. I have a small server I play on which has only about 80kB/s upload i.e. it lags every time I'm connected to that server from the outside. Especially in minecarts where I regularly experience this behaviour and also died on at least one occasion (but that was because of a really bad connection on client side with massive lags).
