Server Thread Error: Failed to remove config file from tracker!

Featured Replies

Posted

When using Forge version 31.2.0, or 31.1.99, I see several NPEs (Null Pointer Exceptions) after stopping the server. Otherwise, execution is fine. It appears that the file tracker fails to remove some .toml files from the file tracker.

 

I have reverted back to using 31.1.51, which does not have this issue.

 

PLEASE DO NOT BAN ME. I have tried sooo many times to upload the entire log, and it continues to fail. So I have clipped the log file to the pertinent part at the end.
