Question How do I repair a damaged level / world

[Bruce2W]

My current version Paper server began crashing with "The server has not responded for 10 seconds! Creating thread dump" errors.

It does not do this with a new world only with the one my son has been playing for years.

Any suggestions on how to repair a damaged set of world files?

Perhaps I should have been smart enough to create one.

Try removing the region files and adding them back one by one to see if you can identify the bad file.
As long as you are not using custom blocks you can try loading the world up to a single player world and see if the vanilla client will load it. It may be able to correct errant data in the files.
There are also programs like AmuletMC that will allow for editing the mca region files.


P.S. Use a COPY of the files to do this and not the originals. this way you can go back if needed.

P.S.S. I just read your other post and saw the thread dump. Since it is happening as soon as you son logs in, it looks to be the chunks he is loading. I would look at region file r.1.0.mca chunk [1,1] world chunk 33,1. Something around this area is crashing the server.
