I have a ZFS based backup server which rsyncs from a dozen other machines. There is only a single rsync active for any point in time and the system is used for nothing else. It has an amd64 kernel and 4GB RAM. I tried to follow the ZFS tuning guide. For a few weeks the machine works well. Since monday it rsync always hangs when fetching a big logfile from a remote machine. The two rsync processes are in state "zfs:&b" and "zfs:lo" and can't be killed. The other strange thing is that the system is reporting 3367M (!) wired memory. I have uploaded dmesg output and a some additional information at http://static.23.nu/md/Pictures/freebsd+zfs+issue.txt Any suggestions on how to debug this issue?
