Description (last modified by Roman)

We use a little WebSocket.

And sometimes we execute 

kill -USR1 $(cat /var/run/nginx-81.pid)

to reopen logfiles and nginx creates many workers in shutdown mode. But it workers works for a long time and the next time we again reopen our logfiles (1200 file) and than nginx again creates shutdown worker by that some times later the server starts to consume a lot of RAM
