memory problem. is it normal for lamp to use this much memory?


ubuntu natty
apache2 / php / mysql / wordpress

i just upgraded to apache2 an my memory is exploading. i have a 512k memory vps with burstable to 1gig.

i'm currently running over limit with just one website and no load.

does this sound right. could it be a problem with the php or mysql config as far a memory goes?

here is my 'top'

The following command should tell you approximately how much memory you're using in megabytes.
Quote:
free -m | grep 'buffers/cache' | cut -d' ' -f10
