Hi,
first i have 2GB of RAM, there are be 1,6G free
so it should enough toi make the following:

# mdconfig -a -t mallo -s 750m -u 0
# bsdlabel -w /dev/md0
# bsdlabel -e /dev/md0 (create "a" slice to use all free respective first 1=
6
blocks)
# newfs -O2 -U /dev/md0a
mount /dev/md0a /mnt
# cd to_a_place/with/650MB_of_data/
# tar -cf - |( cd /mnt/; tar -xf -)
after ~256MB transferred i get following errors, and the system crashes
horridble....  first it doesnt react of anything, then it does silently
reboot
without a shutdown.......leaves all unclean....

extract from all.log

Any impressions, suggestions or limitations for md with malloc?
This errors occures also if i request to reserve the space by creation....

thanks

regards
