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
