	I'm still getting this when a script executes at 4AM but it works
fine when I manually execute it within 10 minutes after reboot...

panic: kmem_malloc (4096): kmem_map too small: 377487360 total allocated
       at line 341 in file /usr/src/sys/vm/vm_kern.c
cpuid=0;
Debugger("panic")

	I've tried everything else suggested but those panic as soon as
the memory size shows up in the boot sequence.
