Hi Sven,

Both of those reports were me. I suspect the issue may be isolated to the
HPE custom implementation of the ESXi 6.5u1 build. I haven't seen any
similar reports of people using the vanilla 6.5u1 build.

Interestingly none of the fixes that have been discussed work with this
build either. This includes disabling the rx-mini buffer (# ethtool -G
<interface> rx-mini 0) and adding vmxnet3.rev.30 = FALSE to the VMs vmx

The only way I've managed to restore stability is by removing vmxnet3 out
of the equation completely and changing to the e1000 NIC type.
