When i tried to mine stone with a pickaxe the block regenerated in the same place it was, very quickly without leaving any block to pick up. Also the block that I tried to mine would disappear next time i logged on Minecraft

Duplicate of MC-858.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

I confirm this too (for SSP). It occurs rarely and especially with tools with efficiency 3 or 4.

HA! I think it might be a little overkill to run the minecraft_server.jar on server class hardware, and have it be the only thing running. The physical server is running ESX 3.5, and is hosting some other test systems as well.

I'm only hosting this for my family, so at any given time, there are may be four or five people playing.

I'm guessing the problem is with my choice of distro. I'll give MineOS CRUX a shot, and move the world over to that to see if my experience is the same.

Oh dear. A Java VM inside a Linux VM. The advantage of Java is the independancy from any platform

Sorry for the delay. In my instance it looks like it might be a server side issue. Looking at the server.log file, it contains the following message when I'm experiencing the issue.

[WARNING] Can't keep up! Did the system time change, or is the server overloaded?

I'm currently running the server.jar file on a VMWare server, running Ubuntu 12.04 Server. I've allocated 2048 RAM, two vCPU's to the virtual server. The server is running in RAM, and not disk, with 1024M allocated to the ramdisk.

Command line: "java -Xmx2048 -Xms1024 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=2 -XX:+AggressiveOpts -jar minecraft_server.jar nogui"

And now after looking at the line, it could have something to do with having the max memory equaling the total physical memory allocated to java. I'll make an adjustment to the settings to see if anything changes.

Thanks.

I've experienced the same issue. When mining stone (not sure if other blocks are affected) with a pickaxe, the block regenerates similar to what happens when mining near a spawn point. I'll pay more attention to it tonight, since I had originally figured it was just lag from my workstations to the server.

Around protected spawn zone in Multiplayer ?
