Hi, It also might be relevant to note which port you're running. It must be capable of having re and wm interfaces, since you name them, but that still includes a fair bit. I still see no statement which port(s) you're running... Here my brain equated port with ethernet, not with NetBSD port

hello. Mouse's thought is a good one as well. I'll note, for example, it's pretty easy to send a machine to hang heaven with vi(1). Edit a very large file, say one of 3 gigs in size. Then, pick a starting line a quarter of the way down the file and mark it. Move down the file and

hello. I'd be very surprised if the problem is running interfaces in promiscuous mode. Anyone using bridge(4), or vlans, for example, is runing their interfaces in promiscuous mode, as is anyone running a dhcp server, or any sort of arpwatch. I find it highly unlikely that the network

So here's an interesting problem: On NetBSD 8, 9, current, with both ipfilter and with npf, with different kinds of ethernet interfaces (re*, wm*), run pkgsrc/net/darkstat. Pass a lot of traffic (like a week's worth of Internet traffic). Stop darkstat. Machine locks. I've only recently been
