Hi again !
doing test on my server, I make it hang (HN) running two commands like (in to a VE) :
dd if=/dev/zero of=test bs=1024 count=2000000 && time cp test /tmp/test
I was launched two times this command and my CPU reaches 100% and then it was impossible to take the control by SSH.
Its there a especial UBC parameter to restrict this ?? im trying with --ioprio but not seems to work.
Thanks.
