What is the error with pwritev() in nginx when uploading files in php-fpm?

Question

PHP

Good afternoon, colleagues.
I came across a previously unknown error when uploading files in php-fpm.
The script crashes with the following error:
pwritev() "/var/lib/nginx/body/0000000004" failed (38: Function not implemented)
There may be a problem in the file system. Nginx + php-fpm is in the linux subsystem, the code is in Windows 10. I use Windows 10 with the Linux subsystem, in this case, Ubuntu 16.
Someone faced a similar problem?

Windows can't do that. Do not be perverted like that, either run nginx under win, or a full-fledged * nix machine.
