I have a server (with 8GB Ram) and no specific service is running, but 5GB of Ram is used how can I detect what's the thing which uses the Ram that much?
See? 5GB is used, and the most used thing is 0.9%
of the memory. So, any idea how can I free that 5GB?
echo 3 | sudo tee /proc/sys/vm/drop_caches
will free old buffers and such. – Doug Smythies May 20 '20 at 13:46
