I recently discovered a command that will clear out the caches and buffers for linux in the later 2.6 kernels (this seems to be available for sles 10 and higher)
sync; echo 3 > /proc/sys/vm/drop_caches This frees up all the memory that linux is using as buffers and cache and doesn't appear to have any consequences to run it. My question for the list is: Is there any harm in running this command, and if not, what about setting it to run every hour or so in cron, therefore making sure that linux doesn't eat up any more memory then it needs to?
