Hello
I’m using two droplets (1 GB Memory / 30 GB Disk )

In those droplets, i install couple wordpress sites, as a mockup with vestacp and easyengine each respectively. Basically not much of articles. But then i was informed that i’m running out of space, here’s my du -sh * :

168M 22222
53M bcg.binakarir.com
5.1G binakarir.com
128M content.binakarir.com
8.0K html
182M jobs.binakarir.com
19M roundcubemail
339M test.binakarir.com

and here’s for another droplet:

60K bapakibu.com
60K cuadrillaindonesia.com
188K deskhatech.com
420M eratofoto.com
60K este.deskhatech.com
60K esteprojects.com
1.7G file.muaranalitika.com
275M ids.bapakibu.com
108M indonesiaoptimal.org
165M kappamanga.com
140M meutyahafid.info
300K muaranalitika.com
342M sealibrary.bapakibu.com
149M zamrudkatulistiwa.com

Can anyone tell me why

1. a simple wordpress site can have 5.1G size?
2. Why i kept getting out of space report on my monitor and my usage of mysql is so high?

Deeply appreciate any clue.

Thank you in advance.
