Who can say? Newer versions of FreeBSD could be more aggressive in their
memory usage. Other parts of the kernel like the ATA/AHCI subsystem also
use hardware capabilities more fully.
It seems that the kernel is not seeing any panic, otherwise it should
land in the debugger. This points to some hardware problem, especially
since other users are not reporting crashes like you see.
