Hi,

i have Varnish 4.0.2 from official Debian Jessie (not your repo).

cmd: /usr/sbin/varnishd -P /run/varnishd.pid -a localhost:6081 -T
localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s
malloc,64G

so malloc with 64 GB limit.

According to varnishstat:
{{{
SMA.s0.g_bytes 68719421626 . Bytes
outstanding
SMA.s0.g_space 55110 . Bytes
available
}}}

all memory (64 G) is allocated. But that is not true:

{{{
# free -m
total used free shared buffers cached
Mem: 96774 31615 65159 1 0 10205
-/+ buffers/cache: 21408 75366
Swap: 6143 0 6143
}}}

Varnish allocate only 19 G:
{{{

}}}
