I have system cache used a lot of memory after a long time of work with system so I looked for something what might clear the cache.

So these are scripts (available in 2.6.16 Linux core or newer):

• Clears pagecache

sync
echo 1 > /proc/sys/vm/drop_caches

• Clears dentrie and inode кэши:

sync
echo 2 > /proc/sys/vm/drop_caches

• Clears pagecache, dentrie and inode кэши:

sync
echo 3 > /proc/sys/vm/drop_caches

I’m using the last one.
