что сделано
1. fail2ban натравлен на поиск агента "IE 7.0"  - блочит, но не спасает
2. временно location = / { return 200; } - не спасает
3. if ($http_user_agent = "IE 7.0" ) { return 412;}

        if ($http_referer = "") { return 412;} - тож не стасает
4. sysctl - накручен

sysctl -n kern.ipc.numopensockets
90228
