While exploring with a map selected in the hotbar causes the realm to crash in certain areas. All players on the server are also kicked, and no one is able to rejoin the server for about 5 minutes with error "Unable to connect to world". When traveling to area without a map, everything works fine.
*UPDATE* This issue only occurs when a) you venture into the area in which it is occuring; AND b) the map is selected in the hotbar. If you select the map while within the area of the problem, the server will crash. Again, the entire realm crashes; I know this because it kicks all players off, not just the person with the map. I have recreated this problem with two different computers on two different LAN's, and two different realms (one is survival and the other is creative), with the other players either on the same LAN or on seperate LAN's. It is easiest to recreate this issue on creative mode (because of flying), with a 1:16 map (I have had it on both 1:16 and 1:4). I have not been able to figure out why these areas cause a crash. I can go through both areas without a map just fine. Neither one is the same biome (one is a hilly beach area and the other is a swamp).

Had the exact same problem. If map is in the hotbar even not selected game would crash. Happened multiple places mainly near towns. My map was level 4 but have not tried with lower levels maps.
I have tried a couple of things. Firstly, I went to the problem areas and attempted to use an empty map to see if it would do anything. It renders a blank map and then crashes the game. So I downloaded the world to my local computer and tried it from there. When downloaded and played locally, the maps do render without the game crashing. However, while in the problem areas, my CPU usage jumps from around 10% to 70% and the terrain takes about 25 seconds to fully load. My CPU remains running high while in the problem area but drops back to normal when outside of it. What I've noticed is it mostly happens when there are 3 or more biomes within an area. On the attached image you'll notice that the upper right problem area is the intersection for a swamp, forest, and plains. The bottom left is a little harder to tell, but it is an ocean, plain, and forest. However, there are other areas that have 3 biomes with no issue. I have tried looking all around the problem areas and have not noticed a discernible pattern. As Dino Roger mentioned, his problem happens around villages and indeed, both problem areas on my screenshot have villages close by. But there are several other areas with villages that I've explored with no issue at all.
It's Windows 10 beta version. Seed shows as 0 and there is no way to find coordinates. Also, it happens on every seed but only while on a realm. If the world is downloaded locally, it does not crash.
My appologies. You are right. What I meant is that it is nowhere near as complete as the Java version. Once it is, it will be better than the Java version (because Java is a horrible way to create a game on the scale as Minecraft). I too wish that these bugs will be fixed with expediency. Getting angry won't help; giving good and accurate information will.
What kind of information will help with this issue? Do you need more testing or more information to find the exact cause of the issue?
From my experience I am simply unable to create the blank map, or hold it actively in my hands without this happening. I get a few seconds of blank map with a marker for myself when I have done this on accident. I havent' found more than one area that does this and I am still unsure as to how large the area is but I assume it is a single unzoomed map size that is to blame.
Anybody care to specify the biome/biomes they had the issue with?
Mine was the dark forest/mushroom/lush forest biome. Like a Dark oak forest with big mushrooms. It might be on the border of another biome also. If not it is right next to another biome. The area had some exploration and minor building but nothing extensive. no buildings just random blocks placed, torches, chests, misc dirt, stone plants, etc.
A the common blocks are in play all over with no issues.
My thought is if there is a commonality that is not extremely technical, it has to do with the biome? Or maybe the border of 2+ biomes. More were very close it could have been like a biome edge nexus or something! Maybe up to 4 biomes were nearby (in sight).
So anybody else know if biome borders may have been involved in your crash area or anything like that?
My realm appears to have the same issue....creating maps in 1:2 certain ones cause the realm to crash and kick everyone out. I seem to notice this issue in high mountain area.
Please reply and update affected versions if you're still able to reproduce this issue in either 1.0.4.11 or 1.0.5.3.
These are the areas in which the problem is occuring
