php - CENTOS / HTTPD memory issue -


hi running vps (1gb memory) has client site on these specs:

  • wordpress (no cache plugins)
  • timthumb image resize script (http://timthumb.googlecode.com/svn/trunk/timthumb.php)
  • shopp plugin ecommerce (has caching system)

php.ini memory limit set 64m max per script

after restarting apache have around 500m free memory. after visiting client's site in random browser memory drops 150-200m !!

i trying figure out loophole, might overlooking obvious awnser please advise :-)

i'm assuming you're on linux vps, ... how looking @ 'free' memory? there's few different measures of in average linux system. instance, linux box, get:

marc@panic:~$ free              total       used       free     shared    buffers     cached mem:       2058188    1596532     461656          0     778404     604752 -/+ buffers/cache:     213376    1844812 swap:      1052248          0    1052248

by first line, appear 1.5gig in use , under 500meg free (on 2gig box). however, totals include memory used disk cache, second line. once remove cache buffers counts, 213meg of memory used running processes, , 1.8gig free.
