Hello Wolfgang,

I am trying to repro your issue. The file is ~140gb so doing a `bzcat` takes a long while. Will get back to you with the result.

For now, here is the sha1 hash of that file so that you can compare against your local copy, see if it was corrupted in flight?

$ sha1sum wikidatawiki-20240101-pages-articles-multistream.xml.bz2

Hello!

I am having some unexpected messages, so I tried the following:

curl -s https://dumps.wikimedia.org/wikidatawiki/latest/wikidatawiki-latest-pages-articles-multistream.xml.bz2 | bzip2 -d | tail

an got this:

bzip2: Compressed file ends unexpectedly;
        perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
        Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

The first part is an error message which I could also see when running my PHP-script from within the toolserver-cloud (php 7.4 because class XMLReader with the installed php 8.2 simple core dumps, see T352886). The second part is the output from the "tail" command.

Just as a crosschek: I have no such problem with
curl -s https://dumps.wikimedia.org/dewiki/latest/dewiki-latest-pages-meta-current.xml.bz2 | bzip2 -d | tail

No error and the last line is "</mediawiki>"

Cheers,
Wolfgang
