I'm attempting to transfer a large amount of data from one zfs pool on one system to a zfs pool on another via zfs send/receive. The sender is 8.2 and the receiver is 9.0. The receiver is using a re network driver, and sometime during the transfer all connectivity is lost with the receiver. Looking at the machine, I see: re0: watchdog timeout re0: link state changed to DOWN re0: link state changed to UP every 5-15 seconds in the logs. I've tried disabling MSI/MSI-X, but that didn't have an affect. The only way I've gotten connectivity back was to reboot the machine. Has anyone seen this before? Any ideas? pciconf of the network interface: vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8111/8168B PCI Express Gigabit Ethernet controller' class = network subclass = ethernet cap 01[40] = powerspec 3 supports D0 D1 D2 D3 current D0 cap 05[50] = MSI supports 1 message, 64 bit cap 10[70] = PCI-Express 2 endpoint IRQ 2 max data 128(128) link x1(x1) cap 11[b0] = MSI-X supports 4 messages in map 0x20 enabled cap 03[d0] = VPD ecap 0001[100] = AER 1 0 fatal 0 non-fatal 0 corrected ecap 0002[140] = VC 1 max VC0 ecap 0003[160] = Serial 1 1234567812345678 Rob
