quite a lot of memory. on i386 you simply can't allocate >4GB VM.

but i have larger volumes without problems.

what was your newfs options when creating it.

of course you did man fsck_ffs ? :) default options are NOT good, 
overallocates inodes, and possibly needs that amount of ram because of 
this.

if your machine is 64-bit capable use amd64 not i386 version - no 4GB 
limit.
