Ive been through the tuning man pages a few times, everything seems to be ok However i could be missing something
Im am not tracking the 4.8-STABLE, this is just from some point
here is the full backtrace, any more help is greatly appreciated

Subject: Re: 4.8-STABLE kernel crash
The instablity has been for a few months, but prior to that, the box was up
over 140 days without a single problem, no hardware changes
since. I think i recompiled allowing ipfw after that, but nothing else major.
In the absence of a full backtrace here are some guesses at possible problems:
1) You seem to have 1G of RAM. Please check that you've set the memory related loader tunables accordingly. You may want to set the value of the kern.maxusers sysctl to below 256. See man tuning(7).
2) Are you tracking the 4.8 RELEASE branch, or is this kernel from some point on 4-STABLE?
Notes: If you are using loadable kernel modules, please ensure that the kernel and modules are compiled from the same source revisions.
It may be helpful to get a full kernel backtrace from a dump. The steps to do obtain this is present in the Handbook.
