Details

In ESXi host environments running QLogic QL411XX Nics on qedentv driver you may experience network interruptions.

The following must be performed/observed to determine if this a driver issue:
-    Correlate netqueue add/delete messages over a period of time and see if there is a pattern of rapid netqueue add/delete occurring on a specific netqueue.
-    Additionally there could occurrence of packet discards due to no receive buffers – and these will increase when the filter is applied to the netqueue that is not operating correctly
-    The failure messages from entities like NFS/vSAN that may be impacted will occur only when the instantiation of the problematic netqueue happens.

You may see an increase netqueue add/delete occurring on a specific netqueue.

This can result in packet discards due to no receive buffers. This condition will increase when the filter is applied to the netqueue that is not operating correctly

~ # esxcli network nic stats get -n vmnic0

...
Receive missed errors: 34871289
...

This problematic netqueue condition can impact any service utilizing the network stack, i.e., vSAN, VMotion, NFS, and virtual machine networking. It is possible that this condition is linked to physical CPU overcommitment.

Solution

This is a known issue with current driver versions on the VMware HCL. The issue is resolved in the following version of the driver

ESXi 6.0 : Version 3.9.17.0 (Apr 10, 2018)
ESXi 6.5 : Version 3.9.17.0 (Apr 10, 2018)
ESXi 6.7 : Version 3.9.17.0 (Apr 10, 2018)

FW version 8.33.14.0 recommended with this driver.

As this driver ion is not on the HCL, it is recommended to open a case with the HW vendor to have the issue confirmed so they can provide driver if applicable.
