Rotation Freezing Bukkit Server

[mrghorm]

Movecraft V 3.1.X50 is freezing bukkit version 1.7.9-R0.2 when any vessel of any type is attempted to be rotated. I've tried this with several different kinds of vessels with different materials, and regardless of everything, when a rotation is attempted, the server freezes. Multicraft stops the operation after a "java.lang.OutOfMemoryError: Java heap space" error.

I've tried this same thing with a smaller server running the exact same versions of both bukkit and movecraft; works fine. Compatibility mode is enabled on both servers.

The two main differences between the two servers are; The large server is running multicraft and the small server is not, The large server is equipped with other plugins like Essentials and Worldedit whereas the small server is not.

Props for the amazing plugin!

[Baccayarro]

I've been trying to test this, is it possible that the chunks had to be generated? Were you doing this testing in an area that may not have had nearby chunks generated, IE: a new area on your server?

I'll keep looking.

[Baccayarro]

A little more info: What is happening is that Movecraft sees that the chunks that the craft is rotating into were not loaded, so it starts to load them. That's where it crashes. It also seems from this trace that it is trying to generate a chunk.

What is strange about this is that it is very odd that the chunks were not loaded unless you were controlling a craft remotely using redstone. I mean, if you are standing on the craft, the chunks should have been loaded. So it makes me wonder if some other plugin is interfering with the way chunks are accessed, or making the chunks look unloaded even when their not, or something.

[Baccayarro]

Nevermind, I think I have found the problem. Expect a fix soon.

[Baccayarro]

You can get the fixed version here:
https://dl.dropboxusercontent.com/u/11164014/Movecraft.zip

It also includes several new features

[Baccayarro]

Sorry, I must have messed something up in the new build. I'm a little under the weather today, hard to focus. I'll get it fixed ASAP

[Baccayarro]

Ok, it should work now.
https://dl.dropboxusercontent.com/u/11164014/Movecraft.zip

If you want to learn about the new features, I made a youtube video for it:
https://www.youtube.com/watch?v=mpAjuUvQarE

In short it now has WorldGuard integration, a bunch of useability improvements, and more supported blocks than before.

[Baccayarro]

Any word on this? Is it working now? I would like to close this issue.
