Use etop to measure memory usage accurately. Ex:
/usr/local/lib/erlang/lib/observer-0.9.7.4/priv/bin/etop -node
<your_node_name> -setcookie <your cookie> -tracing off -lines 30 -sort
memory

Subject: [erlang-questions] Erlang beam memory question
Hi
If I do the 'top' then the beam is using
Size: 302M RSS: 302M SHARE: 1716
However, when I do the erlang:memory()
[{total,13418553},
{processes,3778222},
{processes_used,3386662},
{system,9640331},
{atom,590253},
{atom_used,580770},
{binary,218737},
{code,6708906},
{ets,834788}]
It is showing different number? Why there is such a discrepancies?
I am running Yaws on OTP r10b-9. I do see the issue once i do stress testing
using tool to generate about 500 user sessions.
regards,
