Otto ,
This is the error i get:
It starts booting , and it starts fsck , it fails with /dev/rwd0e and rwd0h,
(i could see once that when it finished it says:)
fsck_ffs in free(): error: free_page: pointer to wrong page
fsck: /dev/rwd0h: Abort trap
I reboot it again many times and that did not show again
i try to fsck manually like this as you say and i get:
# ulimit -d unlimited
# fsck -y /dev/rwd0e
INCONSISTENT CGSIZE=16384

Start by showing the error messgae. A segmentation fault is something
different than running out of memory.
If fsck segfaults, I need a proper error report.
See http://www.openbsd.org/report.html
If fsck runs out of memory, increasing ulimit -d might help, like:
# ulimit -d unlimited
# fsck ...
That reminds me to cook a diff to do this automatically. With
filesystem getting larger an larger, more people will run into
out-of-mem situations.
