Hello everyone,

I have one server with 2 exon 2.4G Hz and 3G memory, but after one long
time, I find almost all the physical memory is used and only 15M is free, so
that my server is very slow. I know these used memory is not used always but
not cleared after use, How should I free the used physical memory?

Have a good day!

B.R.
