X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 01 Feb 2009 08:24:27 -0000 I'm running current as of 20080130 on an amd64 box. I can make processes stuck in zfs->io_ (output truncated in ddb and top) when I make some packages via ports tinderbox. The ports tinderbox access local disk via nfs (I also tried nullfs). ddb output of ps and alltrace can be found at http://www.rafan.org/FreeBSD/zfs/textdump.zfs.20090130.txt Any ideas? Thanks, Rong-En Fan
