You need to change the maximum limit; this is best done by modifying login.conf(5) (and rebuilding the database). One of the uses of these limits is as a security issue, so the user can't raise the limits above the given maximum level themselves. At .5GB, though, you may be hitting a kernel limit; I know that MAXDSIZ defaults to something like 128MB. Getting to 4GB on a 32-bit machine is probably not practical anyway. I'd recommend using something more efficient than mirror, or at least figuring a way to break the replication up into smaller pieces. A half-gigabyte is a ludicrous amount of memory space to be using for any such task. [I kind of suspect a memory leak in the application, based on those numbers.] Good luck.
