Hi. I've run across an error while downloading dumps, which I've not seen before. (I've been downloading dumps regularly for over 5 years). I've done some research on it, but haven't found much information. It's a bit random, and from what I can tell, it's not failing for client-side reasons. I'm a bit stumped, so I'm reaching out for any help.
I provide more details below. My quick questions are:
* Has anyone else run across this error recently? Or just random failed downloads? I've first received reports of it on July 29th, and encountered it myself several times today. * Has anything changed recently on the Wikimedia dump server side that might require TLSv1? Or anything similar?
Any detail or feedback would be helpful.
Thanks.

I'm downloading XML data dumps from https://dumps.wikimedia.org through XOWA. Recently, random downloads fail with a javax.net.ssl.SSLException: "SSL peer shut down incorrectly"
Some details: * This seems to happen more often when downloading large files. I ran across it five times today on an openSUSE box. Each file was over 5 GB. ** https://dumps.wikimedia.org/commonswiki/20160801/commonswiki-20160801-pages-... ** https://dumps.wikimedia.org/commonswiki/20160801/commonswiki-20160801-image.... ** https://dumps.wikimedia.org/enwiki/20160801/enwiki-20160801-pages-articles.x... ** https://dumps.wikimedia.org/enwiki/20160801/enwiki-20160801-pagelinks.sql.gz * In addition, I know of one other person who also encountered this error several times. This person was downloading Polish Wikipedia, and encountered it on both Windows and Ubuntu. I believe they were in a different part of the world (Poland vs East Coast United States) ** https://dumps.wikimedia.org/plwiki/20160801/plwiki-20160801-pages-articles.x... * This error does not occur when initiating the connection (at handshake). It occurs sometime during the download of the file (for example, at the 85% mark). The actual percentage appears to vary (i.e.: not always at the 1 GB mark)
Some other observations: * Restarting the download for the file seems to work, but that may have just been "luck" * I've downloaded other 5+ GB files without problems. For example, https://dumps.wikimedia.org/wikidatawiki/20160801/wikidatawiki-20160801-page... . Again, this may have been just "luck" * I've downloaded other "smaller" files such as the pageprops file without problems. * I've tried running the Java application with "-Djavax.net.debug=all". This provides a lot of info, but nothing particularly interesting. It seems to confirm that the server requires TLSv1 (and not TLSv1.1 or TLSv1.2). Furthermore, I haven't been able to reproduce the error while this debug flag is running.
