Saya terus mengalami kesalahan seperti ini,
[02-Jun-2012 01:52:04] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 19 idle, and 49 total children

Saya mengubah pengaturan untuk php-fpm ke ini,
pm.max_children = 150 (It was at 100, i got a max_children reached and upped to 150)
pm.start_servers = 75
pm.min_spare_servers = 20
pm.max_spare_servers = 150
Yang menghasilkan
[02-Jun-2012 01:39:19] WARNING: [pool www] server reached pm.max_children setting (150), consider raising it
Saya baru saja meluncurkan situs web baru yang mendapatkan jumlah lalu lintas yang cukup besar. Lalu lintas ini sah dan pengguna mendapatkan 504 batas waktu gerbang ketika batas tercapai.
Saya memiliki koneksi terbatas ke server saya dengan IPTABLES dan saya menjalankan fail2ban dan melacak log akses nginx. Lalu lintas semuanya sah, saya hanya kehabisan ruang untuk pengguna.
Saya saat ini berjalan pada kotak dual core dengan ubuntu 64bit.

Apa yang bisa saya lakukan untuk berhenti kehabisan koneksi? Mengapa ini terus terjadi? Saya memantau lalu lintas saya di Google Analytics secara realtime dan ketika jumlah pengguna di atas sekitar 120 php-fpm.log saya penuh dengan peringatan ini ..
