re: kern/43877: named hangs with 5.99.39 kernel, 5.99.27 userland

[matthew green <mrg%eterna.com.au@localhost>]

i saw this on sparc64, too.  i thought it was the old sparc vs pthreads
vs.  bind issue, and disabled pthreads in bind and it make my bind work
again.  i have a small patch to the bind build to fix the
NAMED_USE_PTHREADS=no setting again i plan to commit once i've confirmed
it doesn't break anything else.  (see below)

in my case, i didn't get to starting named because dhcpcd tried to run
"dig" which never exited for me, and my boot hung there.
