Sorry for this last mail. I have found another mistake, but I
don't know if this bug comes from iscsi-target or raid5 itself. iSCSI
target is disconnected because istd1 and md_d0_raid5 kernel threads
use 100% of CPU each !

Given that the summary shows 87.4% idle, something is not right. You
might try another tool, like vmstat, to at least verify the way the CPU
is being used. When you can't trust what your tools tell you it gets
really hard to make decisions based on the data.
