Re: random lockups

A different machine has locked up, running recent netbsd-10.  I was
doing pkgsrc rebuilds in zfs, in a dom0 with 4G of RAM, with 8G total
physical.  It has a private patch to reduce the amount of memory used
for ARC, which has been working well.

All 3 tmux windows show something like

  [ 373598.5266510] load: 0.00  cmd: bash 21965 [flt_noram5] 0.37u 2.89s 0% 6396k

and I can switch among them and ^T, but trying to run top is stuck (in
flt_noram5).  I'll give it an hour or so, and have a look at the
console.
