Looks like the file descriptor error is causing your problem. It sounds
like, when your system tries to open the WebSocket session with the
browser, the OS isn't creating the handler for it. Maybe the user has too
many file descriptors open?

Can you give some more details about the system you're running this on?

Ok,

I´m using Ubuntu 16.04.1 LTS:  4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6
17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Even in successful connections this "file descriptor" error appears.

Where can I look at how many open files I have?

Are there any other errors in your catalina.out?

What about in the browser's JavaScript error console?
