I am sharing out ZFS ISCSI luns to my Mac. When copying large files, the
network will hang in the middle of the transfer and the LUN will become
unavailable until I plumb the NIC. This issue appears to only occur only when I
am reading files (ie..syncing an ipod) and not writing (I'm not 100% sure
though). When I snoop the interface I notice a bunch of ARP lookups. Any ideas?
Thanks in advanced.
