Thank you smokingwheels for sharing a part of your threads dump. For this case this may be more helpful than the logs (for now, I did not found any clue about the issue by reading them). Can you share the full threads dump?

By the way, the part you shared may suggest there is a problem with file handlers. I already started cleaning up potential leaks in code dealing with FileInputStreams (https://github.com/yacy/yacy_search_server/commit/d98c04853dd39a452b0b98fb269a2013396cbb42 [^]). But there are probably other code paths to improve, notably the ones using RandomAccessFiles.

Ok Thanks.
I think there is a problem when doing a shutdown while crawling, it leaves the crawler Que's open on disk or something.

Clone and Run as root doing a crawl then shutdown Yacy.

I used chmod -R 755 /usr/yacy... then as a user moved Yacy's files to different place it still crawls when started but the 0003.stacks and folders have errors with cut and past they are all left behind.

Possible Fix is to create a crawler stacks index counter file separately thus retain compatibility with earlier versions, for times someone uses pkill java to terminate it.
