itu child process dari mysql saja, vpsnya masih normal kalau dilihat dari command top diatas
mungkin yg diperlukan adalah tweaking mysqlnya sambil berjalan, sebab untuk mysql tweaking lebih mudah secara live jd bisa diatur parameter apa yg perlu diubah dari my.cnf

lha itu masalahnya mas
saya pake webuzo, my.cnf isinya cuma gini doang
Code:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
bingung tweaking nya

itu berarti serba default,
misalnya saja untuk default "max_connection" adalah 200 maka ini terlalu gede
jadi coba browsing "small my.cnf" lalu masukkan ke situ

harusnya walaupun default dari mysql isinya tetap banyak. g pernah pakai webuzo jd g tau seluk beluknya, soalnya beberapa panel menempatkan confignya di direktori yang lain.
kalo udah nemu config yg saat ini dipakai mysqlnya, selanjutnya bisa coba tweaking dengan mysqltuner.

kalau vps dengan ram 512 mb lebih baik tidak menggunakan panel, atau kalau menggunakan panel pelajari dulu config-config yg dibuat oleh panel tersebut. selanjutnya nanti akan terbiasa menginstall webhosting tanpa bantuan panel lagi.

panel webhosting itu efisien untuk digunakan/memudahkan, kalau untuk mengelola domain dalam jumlah yg sangat banyak

ini saya coba upgrade ke vps 1GB, tanpa panel
tapi kok child process mysqlnya banyak banget

yg paling besar diambil oleh node (saya coba pake ghost, blm nemu optimasinya, jadi cuma run standard aja, belum optimasi)
'anak2nya' mysql, jumlahnya banyak sekali
normal gak tuh mas?

Sudah coba direboot?.
sudah pak, tapi cuma turun beberapa menit
berikutnya naik lagi

Lha itu max_connectionnya masih ter-comment.. di uncomment dong... trus ubah nilainya dari 100 menjadi 20.. lalu reboot mysql service-nya.
kl mau yang lebih kecil penggunaan memory-nya bisa pake MySQL-nya Twitter... https://github.com/twitter/mysql
atau bisa pakai MariaDB / Percona / Drizzle
Mungkin referensi berikut jg bisa membantu :
http://lowendbox.com/blog/reducing-mysql-memory-usage-for-low-end-boxes/

eh iya..gak ngeh mas :confused:

pernah sih baca artikel tentang mysql twitter
tapi belum pernah coba
ada tutorialnya mas?
saya search di google gak nemu tutorial mysql twitter, yg nongol malah artikel cara twitter menej databasenya

=====================edit==================
eh iya bener, habis nurunin max_connection + ngikutin tuts leb + restart
sekarang jadi 'adem'
