[Asterisk-Users] memory consumption

[Martijn van Oosterhout]

You should good for a better explanation, but here's the gist:

1. Free memory is wasted memory. You paid for it so obviously it should
be used. Modern operating systems turn your "free" memory into disk
cache. So the actual amount of memory available is the combination of
free, buffers and cache.

2. Secondly, asterisk uses threads, so all of those processes are using
the same address space and have the same amount of memory. Due to
memory being shared in various ways, the values in top will likely never
add up to anything resembling your actual memory...

Hope this helps,
