 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:
 {{{
