      Description

      See [Mod] Marcono1234's comment for the reason and more ways to reproduce


      I'm not sure, but somehow strange errors occure when using /blockdata which added a tons of backslashes (escaping sign in JSON).

      I needed a setup where a repeating block makes a testfor continiously, but runs a chain of command blocks in case of true only once.
      (comparable to repeating -> comparator -> command block, but I don't want any redstone)

      So following setup (imagine a tower of command blocks)
      1. Repeating (A): Testfor something, if true, run (B).
      2. Chain, conditional (B): Sets blockdata of an impulse (C) directly above to auto:1b. (C) will not, of course, take any "signal" from (B) because it's not a chain cb.
      3. Impulse (C): If (A) was successful, (C) and other chains (C2,C3,C4 etc) connected to (C) will run now ONCE (as (B) has set this block to auto:1b - so until here everything is working as expected and wanted).
      Because (C) is in the "Always active"-state now, I need to reset this, so it would run again if (A) is true again.

      How did I do this? (Now imagine a second command block tower, just right next to the first one; x-axis plus 1)

      1.1. Repeating: This block checks if the repeating (A) from the first tower is false (by using testforblock and SuccessCount)
      2.1. Chain, conditional: If 1.1. is TRUE (and A therefore FALSE), this chain will now run exactly as B did and sets its block above to auto:1b.
      3.1. This impulse will now set its neighbour (C) back to auto:0b. (C) itself will do this exactly the other way and sets 3.1. back to auto:0b, as soon it is activated.
      So these towers will reset them each other depending on the success state of the very first repeating block (A), but only run once.
      (See screenshot, I think it is easier to understand then).

      So far, so good. Now what happened is very, very unexpected. I was working on the map for many hours, everything was working fine as I wanted, just until the game began to lag. The FPS dropped from 60 to 10-20 until the game completely crashed.
      For the first time, I just restarted the game, loading the world again. But nothing, until the game tried to save. Then the lags returned, followed by a crash again.
      So I took a look into the logs (not the crash log, in order to look for the reason), finding the line

      [File IO Thread/ERROR]: Failed to save chunk
      java.io.UTFDataFormatException: encoded string too long

      The crash logs said:

      After using Google I found out that this error is related to problems with JSON parsing. So I took a closer look to my command blocks (as this was a void map, there was not much to check).
      And then this: In the "Last Output" fields of the command blocks containing the block state auto 0b / 1b thing, there was a giant line of backslashes.

      [21:37:17] The data tag did not change: {conditionMet:1b,auto:1b,CustomName:"@",powered:0b,Command:"/blockdata ~1 ~ ~

      (The bug report doesn't even allow that much chars...)

      This was not only the case in one of the "pairs" I set up, but in every /blockdata with the auto 0b / 1b thing.
      As the problem did not occur directly, but hours later, I guess that these backslashes came up after some time and stacked more and more.
      No wonder that the memory got an overflow. But I really cannot imagine what I've made wrong, as the bug did not occur immediately...

      Update: Uploaded a demo world: The problem does occur soon if you provoke it.
