What file system are you using? Do a full fsck (or zfs scrub). Try moving swap to a raw (freebsd-swap) partition so that you might get a kernel core dump. That will be the essential next step. Without more details from a core dump or debugger, your best option is to try a release or an older build. If that works, try to find the commit that introduced the behavior. This will be very tedious and time-consuming for your scenario, so definitely try getting a core dump first.
