Nginx mati - bind() port 80 dan 443 failed

[anasmcguire]

jam 10 siang tadi, website saya(Trafik website 8k/hari) tiba-tiba mati. Saya pakai nginxproxy, php-fpm_event. Saya cek service ternyata nginx saya mati. Saya ganti mod-php_ruid2 pun tidak bisa alias gagal, akhirnya saya gunakan nginx murni. Website up kembali. 

Di log nginx error terdapat:

Code: [Select]

Itu kenapa ya? Apakah memory saya tidak mencukupi atau overload? Bagaimana cara mengatasinya agar kejadian ini tak terlulang kembali terutama ketika saya menggunakan nginxproxy php-fpm_event?

Coba kembalikan ke nginx-proxy dan bila mendapat error yang sama coba lakukan reboot.
