1.14.1

Update 20190518@07:17: creative server is also up on 1.14.1.

Some strangeness was causing frequent crashing after we updated to 1.14. I have now updated the survival server to 1.14.1, which (so far) seems to have solved the problem. I’m going to leave the creative server offline until I’ve tested 1.14.1 a bit more.

The 1.14 Update

I have updated the creative and survival servers to 1.14.

For now, the minigames server is down. Nobody has really used it in a long time, and I need the hardware for another task (one that actually, well, makes money). If anyone misses it, drop me a line and I’ll bring it up on another box.

The survival server map might remain out-of-date for a bit while we get overviewer working with 1.14.

1.13.2

All active servers (survival, creative, minigames) have now been updated to 1.13.2 — have fun!

minigames back up

The minigames server is back up, and can be reached (as always) at minigames.twoprops.net — thanks for your patience. The new server is about ten times faster and lightly loaded (right now) so performance should be excellent.

miner (and minigames) down

miner.sacdoc.org, the server that currently hosts the minigames world, is down and out. When I opened it up, I found a bracket I had fashioned from a wire coat hanger to fix a broken CPU heat sink in the days before you could rapidly get replacement parts shipped overnight online. The server was old then, and that had to be ten years or more ago.

(The box was named “miner” not after Minecraft, but because I used it to mine bitcoin with a graphics card back when that was a viable option.)

I’ll resurrect the server data onto a new, more modern box. minigames isn’t much used, but it’s historically of interest to me as are a number of other worlds that are on the box but not currently live.

re-rendering

I’m currently running the latest testing build of overviewer. It’s been going for about 12 hours, and says it has 31 hours to go. Once it’s done, most of the missing blocks should be restored.

Update: rendering complete (20180826@11:53, 27 hours rendering time), new map is live. Most missing blocks appear. The only anomaly I have noticed thus far is that rail is not oriented properly. Well done, Minecraft Overviewer team!

cleaner server/cooler server

In response to the apparent overheating problems when running Minecraft Overviewer, I installed software to monitor the CPU core temperature. I found that it was hovering around 40°C at idle. When I ran overviewer, that would climb to the low 90’s, but the system never shut down (which happens at around 127°C, I believe). So I enabled the nightly cron job to update the map, and all went well for a few days. Last night, the server shut down again.

overviewer overheating?

The initial run of overviewer seemed to work well. Yesterday, I re-enabled the cron job to update the map every day at midnight. When I got up this morning, I discovered that the server had died at 00:16.

I restarted the server and tried updating the map by running overviewer from the command line, and the server switched off abruptly after a few minutes with no error messages.

There’s nothing in the logs, and the server doesn’t just die, it powers off. The most likely cause is that the processor is overheating, but it seems odd that it completed the initial build during several days of triple-digit temperatures with server room temps reaching the mid 80’s, and last night the temp in the server room was in the low 70’s. But CPU fans and cooling paste can fail over time, and perhaps overviewer actually taxes the processor more when most blocks are already up-to-date.

Right now the server is running, but the maps won’t be updated until at least the weekend when I have a few moments to troubleshoot.

overviewer

Some amazing volunteers have been updating Minecraft Overviewer to work with the new 1.13 file format. I am running a test version now. It estimated sixty hours (!) to render the new map from scratch, but it’s going a bit faster than that.

UPDATE: The rendering is finished (in just under 30 hours) and the new map is installed. As expected, there are blocks that don’t render but overall it looks good. Check it out!
