Hi,
I've been using an APU2 with OpenBSD as my home wired/wireless router
for a couple of years now.
Initially I used bridge(4), and never experienced any problems. About a
release ago I replaced bridge(4) with switch(4). It works just the same,
except that every so often my net goes down for seemingly no reason,
because switchd has exited.
"rcctl start switchd && switchctl connect /dev/switch0" starts up my
network again, but switchd always exits again, within a few minutes or
hours or days or weeks. I've never noticed any direct cause or been
able to reliably trigger it, although I'll say it seems to happen
more often with lots of traffic (e.g., torrents or large HTTP
downloads).
I ran switchd -dvvv with script(1) and got a huge typescript, ending
in the following (more context available if necessary):
