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?

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
