Hi.
I've been experiencing similar lock-ups on DragonFly NFS server since
the recent changes to the network code.  Similar, but without objcache
warnings as in the previous messages.  I can reproduce it on multiple
machines and it occurs even when mounted via loop-back interface:

  $ sudo mkdir -m1777 /test
  $ sudo mount -tnfs 127.0.0.1:/test /mnt
  $ env MAKEOBJDIRPREFIX=/mnt make -sj300 buildworld
  (leave it for a couple of hours to find many processes stuck
   in ZOMB state)

Probably it can reproduce with much lower -j number to make command.

Best Regards.
