Httpd Sering down di VPS dengan panel webmin

[cyberidiot]

malam,

new bie mw nanya nih, saya ada vps untuk game server ada web control panelnya, webnya suka tidak bisa di akses, sedangkan kalau habis jalankan

# service httpd restart

di putty maka webnya bisa kebuka, setelah beberapa menit dicoba, webnya tidak bisa dibuka kembali. masalahnya di mana ya? saat web tidak bisa di akses, saya bisa buka web phpmyadmin maupun webminnya, karena beda port, nah yang masalah kyknya di port 80 / httpdnya.

sudah:

# chkconfig --levels 235 httpd on

juga, gimana ya solusinya? VPS nya OpenVz

apakah ada yang flood ke port 80 web saya?


Makasih

utk bisa membantu analisis lbh lanjut bs diinformasikan jg om, gimana spec server dan kondisi website yg dihostkan disana (traffic),
klo pengalaman saya pribadi biasanya httpd down pd saat tjd cpu spikes dan memory usagenya tinggi krn lonjakan traffic pd jam2 sibuk ^^

cb jalankan command ini utk melihat request yg masuk ke port 80 utk deteksi dini adanya ttack

netstat -plan | grep :80 | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

MaxClients di httpd.conf = 1000

sebelumnya 256, dinaikan juga sama saja..

Coba check memory Tuan. "vmstat" atau "top" nanti keliatan memory status nya gimana. Mungkin bisa diposting disini memory statusnya, nanti coba kita simak sama2

kalau saya pakai nginx yang sering down fcgi nya. jadi harus start ulang tiap beberapa menit lewat cron.
apa mungkin bisa disamakan untuk kasusnya om ya buat start httpd nya?

saya pakai virtualmin, yang jelas pakai webmin didalamnya
masi nunggu penerapan php-fpm buat pengganti fcgi..tapi belum rilis2 dari virtualmin :S
