I have received several private comments expressing interest in this topic, so I'd like to generate more discussion and attempt to focus on a solution that meets most or all of the needs. Summary of problem: - A zone can be configured so that its processes do not run on the CPUs in the default

Many thanks to Bob Netherton and Jeff for their quick help on that painful issue. The solution was to use psrset -f on the heavily used pset. It is fully supported and a recommended situation when CPU starvation causes interrupts not to be serviced in time and they get lost. Credit goes to Rick

Hello Got a zone running SAS with cpu capping enabled using a processor set as we see a few processes using quite a bit of cpu there too often. When the process is running (chewing 100% of its pset), the frame nic (server is a E2900 with a ce interface) is dropping 20-30 % of its packets causing
