 **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.
