Just thought I'd throw this up on the forum in case you guys had seen any similar issues.
When copying data OFF the Qnap on either interface, we get a shit ton of dropped packets on the *receive* side. Makes no friggin' sense unless the Linux kernel on this box is sharing buffer space for TX and RX. The Qnap forum people keep telling me to disable jumbo frames, and I've already established that's not the issue. The interfaces on both Linux boxes these connect to don't show any dropped packets. Suggestions? (Other than buying a netapp...)
