**SOLVED**
So after some testing it seems like the problem is indeed related to the
pecl-APC-3.0.19 port we are using. The default configuration option for
the port is to use "Locking type = File locks." We recompiled the APC
extension from source with the flag "--enable-apc-spinlocks" and now
everything's working like butter. So it appears that there is a
conflict with the pecl-APC port's default configure settings and FreeBSD
SMP? Either way it's working great now. A big thank you to "pav" for
making me realize the kernel panic was referring to UFS Locking.
