That's a SIGSYS "non-existent system call invoked".  However, in this
case it probably means that either there's some sort of hardware
problem with your system or that your system is not capable of running
a recent version of FreeBSD -- 8Mb is cutting it pretty fine: probably
too fine.  Check the archives, but I believe you need at least 12Mb to
install 4.x.
