caching - centos os - apache httpd takes all my ram and cache -
i have 2 sites on machine getting unresponsive/slow.
i checked on vps (virtual dedicated server) used
#free -m
, got this
total used free shared buffers cached mem: 992 926 66 0 3 24 -/+ buffers/cache: 898 94 swap: 63 0 63
i read http://www.linuxatemyram.com/ , im pretty sure not case because cached 24mb, if flush cache with
sync; echo 3 > /proc/sys/vm/drop_caches
i still see usage way high
total used free shared buffers cached mem: 992 903 88 0 0 9 -/+ buffers/cache: 893 98 swap: 63 28 35
but when stop httpd service with
# service httpd stop
stopping httpd: [ ok ]
then used #free -m
again , got:
total used free shared buffers cached mem: 992 210 782 0 13 99 -/+ buffers/cache: 97 894 swap: 63 39 24
i havent had problem before , didnt add features httpd eating ram/cache.
any advice or tips appreciated, ¿what should for/ do?
