Hi,

We are seeing an increasing amount of dropped RX packets on this and the
partner host. We are running a bonded configuration but I removed the
bonding and tested with single interfaces to see if the RX drops still
increased, of which they did.

We have a mixture of NIC's

Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet PCIe
Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection
Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe

All seem to increase in dropped packets, the host is idle.

Using the Broadcom  BCM5719 as an example.  Over a period of ten minutes
the interface received 2.87kb and dropped 3 additional RX packets.

Other than the original hung task we have not seen any further issues.

We are moving away from sshfs in this setup but are keen to understand
the reason for the dropped RX packets.

Thanks,

Tim
