Looks like your bad memory stick has resulted in some corruption being
written to your filesystems.
What you need to do here is reboot into single user mode (or boot from
install media into a shell) and run fsck(8) on your partitions
repeatedly until fsck reports a clean filesystem. The commands will be
# fsck -f /dev/ada0p1
where you should substitute the correct device name for each of your UFS
filesystems. Those can be read from /etc/fstab. Repeat running fsck on
each partition until they come up clean, then do the next one.
You have to do this with the partition unmounted, or at least mounted
read-only (which is what booting into single user gives you: a way to
fsck the root partition you just booted from...)
fsck will tend to ask you a lot of questions: most of the time you want
to say 'yes' to those questions, but be aware that sometimes that can
result in deleting files. Have good backups, and ask again here if in
