Hi!

Im trying to limit memory usage for jails with the rctl API. But I don't really 
get it.

I have compiled the kernel with the right options and rctl show me stuff like:
jail:jail22:memoryuse:deny=268435456
jail:jail22:swapuse:deny=268435456
jail:jail20:memoryuse:deny=268435456
jail:jail20:swapuse:deny=268435456
jail:jail16:memoryuse:deny=268435456
jail:jail16:swapuse:deny=268435456

but when I try to allocate memory it doesn't seem to hit the limit. Also when I 
run 
# rctl -u jail:jail20
cputime=0
datasize=0
stacksize=0
coredumpsize=0
memoryuse=0
memorylocked=0
maxproc=0
openfiles=0
vmemoryuse=0
pseudoterminals=0
swapuse=0
nthr=0
msgqqueued=0
msgqsize=0
nmsgq=0
nsem=0
nsemop=0
nshm=0
shmsize=0
wallclock=0

it seems that no accounting is done. What's missing? Cant find anything in the 
manuals.

# uname -srm
FreeBSD 9.1-RELEASE-p1 amd64


/Peter.
