Apparently it's not as easy to reproduce as we thought, it doesn't happen on all worlds.
So here's the seed for our server's world: -6720233900416869526
I attached the latest client log file from my experiment with the world. Has lots of errory looking things.
@l3viathan: So… We basically have a missingno way to dupe items now? That brings back so many memories 🙂
More insights!
I deleted the world and unzipped the backup again to try something else: Breaking the item frames attached to the chests, some of them containing blocks, which were rendered weirdly as of the other bug I don't have at hand now, but it's known and appears in the snapshot videos of docm77 and SethBling afair. Anyway, I couldn't break the item frames on the chests, but after I broke the chests (and the item frames with it, obviously), it got better.
I made a screen recording so you can take a look at it, but it's still uploading, will edit this comment.
EDIT: Here's the screen recording, relevant part @ 2min
Nevermind, L3viathan's video and reproduction steps are way better.
So I'm back home now and downloaded our server world from the link I provided (so it's the same version of the backup), and I entered the nether, where I landed way below our nether hub/portals which are around y110.
Anyway: There are >3200 entities, which is way too many and probably enough to force our server to shutdown, my laptop can barely handle it as it is.
Then I did /kill @e[type=PigZombie], which had close to no effect.
Then I killed all Ghasts, which only resultet in one Ghast being killed, so there's that.
Then I killed all item entities, which didn't help much.
Then I killed all the chicken, which yielded errors, but still too many entities.
… In total, I Killed Zombie Pigmen, Chicken, item entities, Ghasts, Skeletons, Magmacubes, but I still see >3100 entities.
In the end, I used F3 too look for where exactly these entities are, and it seemed to be our chests in the hub where materials for the hub construction/tunnels are stored. After I broke each chest, the total entitiy count did not rise dramatically as expected, but stayed the same. I then used the command to kill item entities after the chest was broken to remove all the items, and then the entitiy count dropped. After I broke all the chests and killed all the items, entitiy count is back to normal.
Regarding getting rid of the pigmen: Maybe it's easier to shut down the server, switch to peaceful/difficulty 0 in the server properties, and start the server again? Of course this would "delete" every hostile mob, which may not be a desired result, bit it's probably better than having no nether.
I uploaded the world here: http://dump.quantenbrot.de/wurstmineberg_2014-01-24_08h00.tar.gz
Disclaimer: It's 1.9 GB, and uncompressed it's 3 GB.
Well, our world is over a year old, definitely everything but fresh.
I attached the message the player sees after entering the nether portal, comes directly after the "Downloading terrain" screen.
Server seems to shut down as normal as soon as the nether should be loaded.
The server log does not contain any error messages, from the log it looks like a normal shutdown.
Confirmed, works again, thanks!
Reported the no logfile bug thing
EDIT: …The log thing was fixed by redownloading the .jar, will now try to get to the issue at hand.
Huh, sounds familiar. Could you take a look at your debug log while/after these lagspikes occur? It reminds me of this issue I still have sometimes, and correlates with debug messages talking about very long chunk load times.
Our server has become pretty much unplayable because of this issue.
The past hours have been spent like this:
1) We start the server
2) Everything seems to be oka–OHWAIT
3) A wild io.netty.handler.timeout.ReadTimeoutException appears!
4) Everything stops working, we kill all the processes
5) We try to figure out what's wrong
6) We fail
7) Go to 1)
Please help us Mojang, you're our only hope :/
Same symptoms with similar setup (Iron Foundry) on our server, too.
Disregard everything I said before. It now works after I tried
rm ~/Library/Application\ Support/minecraft/assets/DS_Store (with the filename in Asterisks to match any possible duplicates, but it's too late for me to figure out how to avoid making bold text out of asterisks in here)
I don't know why it didn't work the first time around, and now I feel silly. But well, thanks a lot! 🙂
Still doesn't work for me, get's stuck at the MOJANG screen. The jar version doesn't work either, it just exits.
pastebin of dev console from the launcher: http://pastebin.com/NsEG536t
EDIT: Retried the current .jar: behaves exactly the same as the .dmg version.
Please, any hints?
Same as @Fenhl, OSX 10.10.4 and German keylayout.
