Help needed with possible kernel memory leak (FreeBSD 9.0 Release)

[Remme]

Hi All,

Please help to solve a kernel memory leak problem.
After few weeks searching forums and googling any help is welcome.

Here is the problem description:
We are installed the latest 9.0 FreeBSD with all recent patches.
Ports tree is also up to date.
Host running a nginx, php-fpm, memcached, mysqld, sphinxsearch.
Two WD HDD is gmirrored (each partition).
Also we are using a small ssd for nginx cache and mysql databases.
8 GB RAM.

We have always growing active memory till kernel panic.
(it's takes about 2 weeks till memory leak kills host)

According to top - active memory is always growing but sum of all processes
memory is stable about 3.5 Gb.
So looks like kernel slowly eating all our memory
