They are definitely not zombies. They are processes providing kernel services (thus the name "kproc"). I would suspect that they are asynchronous IO servers. You can verify this with the "pstat -A" command. If you see these processes listed as "aioserver", then that's what you've got. I don't know of any other kernel process that runs as a user other than root. The AIO processes run under the user ID that first requested an AIO operation. However, they continue to provide service to any user making AIO requests.

Hope this helps.
