It's happened again. But with zfsd being disabled, it
meant I wasn't detecting the problem except by indirect 
means. Like "hm why isn't nginx working".

The problem is, one of the things that stops first is syslogd. 
So it's not recorded anywhere.

syslogd is loaded with these flags:

syslogd_enable="YES"
syslogd_flags="-ss"
syslogd_oomprotect="YES"

context is main-n252544-7406ec4ea99 on a rpi4b/8GB.
zfs-on-root. There is no microsd; it boots from usb3.

How would I debug this? In the meantime, I'm re-enabling
zfsd.

thanks,
