hello David. I wonder if you're running into another manifestation of kern/54724, which shows zfs corrupting kernel memory in NetBSD-9. I show the problem having to do with xen, but I now believe the problem is entirely with zfs and it was only coincidental that I ran into it with xen. I left the machine in question, running zfs, for a month, doing pretty much nothing, but when I came back to it, I got weird messages like, proc table is full. There were a lot of process running, but I couldn't determine which one was the one that was "really" stuck, since the number of commands I could run was extremely limited.
