This is a schematic for WorldEdit, are you using MCEdit by any chance (if you are using MCEdit there should also not be a problem)?
Your server may have crashed because of not enough RAM which may be due to too many plugins or worlds or even large schematics. If your server does go down don't restart it straight away leave it to try and load the schematic on it's own even if it appears to be closed the server will still be trying to upload it onto your server (it acts as if closed to concentrate it's power/RAM onto uploading your file).
There also a lot of blocks so if you close your server whilst it's uploading the schematic could seem incomplete and griefed (even though it isn't).
Send me a message if you would like help with uploading it and other stuff with your server.
