MC-27517 Bad dimension sent from server crashes the client Duplicate

Comments

Has to do with going past the first mip level. Anisotropic filtering used to fix this, but the option is gone in 14w25b. Makes me feel like we're still using a texture atlas instead of a texture array, even though that can't be it. Could it? O_o

Confirmed in 14w25b

in 1.7.9 there is a workaround: Anisotropic filtering. When textures go into mip for some reason they have some crazy seam issues that cause nasty flicker.

I do not believe this to be a duplicate, as it is unrelated to both joining and chatting, in spite of nearly identical stack traces. If it is, then this is probably the most valuable out of all the 403 current reports, because it's the only one I see that actually expresses a process for reliable duplication on a vanilla client.

Got it - the NullPointer crash happens for all players in the world at the instant the world goes "bad". At that point, you start getting the Bad Packet IDs.

I don't have OptiFine. I do have MCPatcher only for a 32x texture pack, but given the unmodded server and 100% crash rate of any players currently in the same world, this is still a serious problem.

I still haven't seen anything to suggest that this might be fixed.

--- END ERROR REPORT 9bbe86a6 ----------

Haven't gotten around to grabbing the stack trace for the IOException. We managed to break up some of the beacons near spawn and tp people away, and our bad-packets are happening less. I've never seen this problem on a Bukkit server, and it's possible that injected Bukkit code inadvertently fixes this somehow, so if you're trying to reproduce, test this without Bukkit.

Step two is obviously to make at least 12 beacons in one spot, overlapping, in groups of 4. Each group of 4 should share the same pyramid. Step three is to leave the server on for a while. Uptime seems to matter on this one. The last step is to login and play. It might be a race condition. It might be a particular feature that needs to be used. It might be a bat flying into the effect of the beacon. All I know is that eventually those beacons go bad.

We do have some good news though: Anyone not in the same dimension as the beacons does NOT get disconnected. So whatever the offending packet is (the one sent BEFORE the bad packet ID), it's sent out to everyone in the same dimension. That should narrow it down, right?

Yeah, on other servers we can crash clients on command by sending an invalid block ID, troll level master. But this server we deliberately keep vanilla until a stable Bukkit comes out... and I am the mod, so if anyone's trolling me it's Jeb. Don't focus too much on the 244- the packet IDs are random, and more often than not they'll be unused IDs.

They were in blocks of 4 so they could "share" most of the pyramid. I know that Speed and Jump Boost were active, I can't be sure of the other two. It's highly likely that multiple beacon areas with the same effects overlap. Our pyramids vary from 2 to 3 levels. I was conservative in my 8 beacon estimate; Our spawn actually contained at least 12 (probably 14) beacons. Restarting the server helps sometimes as a temporary measure, but after a certain amount of uptime users logged out near the beacons get disconnected with the dreaded bad packet ID.

When a bad connect happens, a stack trace gets dumped to the console; I'll try to pull one of those from my upstairs computer tomorrow.

We finally tracked this down on our servers - completely unmodded servers and clients are experiencing this issue (duplicate of #MC-984), and it only happens when you login near an active beacon block.

We found the commonality! It's the beacon blocks. We were rocking like 8 around spawn, when we move clear of them or disable them people can login as normal.

I wonder if this is related to [MC-984]? Our users are kicked off with bad packets the instant they login, or negative key lengths, or a number of other problems, and nothing is modded. I hope they fix this, it's frustrating.

...Although, it'd be far more useful if it was a transistor instead of a latch. We can already make same-sized latches with torches, and smaller ones with pistons.

This is an extremely hard-to-replicate bug; it happens with about the same frequency as the bug where the server stops sending chunks. I think there's a little problem way back in how the server queues data to send out. Good luck, I'd like to see it fixed too :/

This is nothing new. A lot of people use torches to clear gravel, but it is also possible to place gravel or sand on top of a torch to "suspend" it. I've also noticed that falling gravel can pass through a wall-torch and still land on the ground. I don't see any priority for this behavior to be fixed; in fact, some really clever/fun traps work based on this mechanic.

Certain servers are having this problem. I happen to know that the servers I'm having this problem with are completely un-modded, and un-modded clients get disconnected with "Bad Packet ID", and sometimes even "Not in GZIP Format" and other errors. Because of the random packet IDs, and because the packet IDs do not correspond to anything in the protocol (I got 0x93, for example), I'm guessing that when reading or writing one of the new or modified packets, an incorrect number of bytes is being read/written, causing the whole stream to become offset. If this is true, there's no way for the client/server to find the start of the next packet, so they just pick the next byte out of the stream, and it turns out to be random.

What's odd to me is that the server seems to work fine for a while, then goes kaput. I guess it's just a very particular feature that needs to be used. We started to have some problems after using and hanging a lot of map items, but I'm not sure whether that's related or just coincidence. There were a lot of things going on at any one time.

The repeater in the bottom left of the picture is pushing direct power into the block in front of it (the one the torch is sitting on). This power bleeds out the side of the block into the wire (because it is direct). Minecraft is working as intended, the bug is in your wiring.
