Seems that one of my machines is now doing this too. Yesterday rdists
to it would mysteriously hang and eventually get aborted by the
sending side. I could still log into that machine via ssh, but that
rdist was stuck.
Just to make sure that it wasn't an ffs corruption bug I went single
user, mounted an NFS /usr and newfs-ed the local one. Then I did a
tar copy from the NFS-ed /usr to the clean local partition. The tar
also hung after a few 10's of megs. The writing tar is waiting on
"biowait" flags 0x4006 according to DDB. (This is even with
"genfs_vnops.c,v 1.29 2001/02/18")
Does this ring a bell for anyone?
