Big Video .mkv php-fpm bug

Steps to reproduce

Download video in mkv format, more than 15Gb, start playback, then leave the video playing, and switch to another browser tab, wait 2 minutes, and go back to the video tab, try rewinding the video, forward or backward, watch htop, see www pool children, which peaks.

Expected behaviour

Tell us what should happen When playing videos> 15 gb in mkv format, when rewinding, www pool children should not multiply so much that they should not lead to a server crash.

Actual behaviour

When playing large> 15gb video in mkv format, in the chrome browser, a www pool is created, if you switch to another browser tab, and after 2 minutes return to the video and rewind it, then www pool children begin to form, reaching the maximum and causing it to freeze server.
