Hi,

Can you tell me which international locale you are using please.

ML uses named pipes to communicate with the processes that analyse the data, on Windows these must be named \\.\pipe\PipeName I can see from your log message that the pipe name does not conform to that convention. If I know the locale I can try to recreate the issue.

Thanks

Hello,
I'm experiencing same problem on almost the same setup: Win 10 x64, elasticsearch 5.6.0, JDK 1.8.0_144. After installing x-pack plugin elasticsearch will not start and outputs this:

No other plugins are installed, no configuration to elasticsearch was made - it is just vanilla elasticsearch with installed x-pack through elasticsearch-plugin.bat. If I remove x-pack plugin, elasticsearch will start with no problem.

Thanks for help.

Anyone?
I tried different JDK versions, tried running cmd as Administrator but with no success.

It seems to be an issue with Windows servers and non-English locales - we are still researching. As a workaround in the meantime, do you have an English-based system or Linux?

We have found the cause of this problem and fixed the code. The fix will be released in future patches of all versions of the stack from 5.5 upwards. At the moment I cannot confirm the exact patch versions the fix will be in, but will update this post when I know, and the fix will also be listed in the release notes.
