Please help me understand where my memory has been consumed?
I have 16GB of physical memory and the OS is 11iv2. From basic analysis i can see ~7gb of memory has been consumed by my app ad OS. But i wonder where the memory is taking... is that chache? buffer? how this can be analyzed?

Check your kernel parameter dbc_max_pct:
kctune -s dbc_max_pct Tunable Value Expression Changes dbc_max_pct 10 10 Immed
50% is the (very bad) default for the buffer cache.

This is what i have for the buffer cache. This value was 20% and i reduced to 15, but still memory is busy.
#kctune -s dbc_max_pct
Tunable Value Expression Changes
dbc_max_pct 15 15 Immed
I suspect a memory leak here. Also i wonder how to tune the M_TEMP which is showing on 'kmeminfo'.
System = 2095248 8.0g 50%
Kernel = 1543670 5.9g 37% kernel text and data
Dynamic Arenas = 1086737 4.1g 26% details with -arena
M_TEMP = 920890 3.5g 22%
