I'm wondering if this memory drain may be due to zpool caching (L2ARC).
You could try and see if it helps of you set a limit on this cache. The
way that I understand it zpool/zfs uses quite a bit of RAM for caching.

There just doesn't look like 32gb of stuff running (more like 5gb

need....

hmm ... (haven't done this in a while ...) I'd suggest you
periodically (once every 10', perhaps) 'pmap' all processes and see
which grow most, and then look at those in detail (perhaps using pmap
-x, or starting those with LD_PRELOAD=/usr/lib/libumem.so ...)
I'm sure other people have better ideas.

Hi,
the obvious question to ask: what's the machine doing?

I have a v40z (although all of my boxes do it) 32gb ram 4 dual
core 885s.
When you restart the server it shows about 27 gb free. Over 12
hours
this
slowly degrades to about 1gb free and I start to notice a slow down.
Once
this drops down to 400mb stuff starts to really drag. Setting the
max
zfs
arc use does nothing. This is using TOP.
If you look at the gnome performance monitor it will say you are only
using
2gb of ram yet there is degradation in performance (I assume for slow
memory
clearing and reuse).
CPU states: 94.3% idle, 1.3% user, 4.4% kernel, 0.0% iowait, 0.0%
swap
Kernel: 7755 ctxsw, 139 trap, 13034 intr, 22379 syscall, 120 flt, 136
pgin
Memory: 32G phys mem, 988M free mem, 16G total swap, 16G free swap
and this dropped below 1gb while I was typing this message.
