We have the ESXi 4.1 over ibm x64 hardware plataforms with 4 nics each. All nics assigned to one distributed virtual switch. Eventually the file server guest (Windows 2003 Server), under heavi duty, have a little disconection, enough to hang a few applications. The guest have one installed vmxnet3 adapter.
While try to identify an solve the problem we see something that culd not figure out certanly. What is "Exception - egress packets" in stadistics of dvPortGroup. We attach an image with a red cirle in the question place.
Plz have an answer... thkz in advance.

Exceptions is catch-all bucket for packets that are not expected. For example, you get a packet with vlan tags outside the allowed range, packets with invalid ethernet header etc.
This is slightly different from drops, which can be caused by shaping or a system temporarily running out memory. You do not see many exception packets under normal circumstances. The exception packets are ultimately defined by each vSwitch implementation. Cisco Nexus 1000v defines its own stats. The only place VMware increments this stat is invalid ether type in the packet.
What i understanding i am getting, its not a packet drop, It will allow the packet with invalid vlan tag???
This case will happen in promisicous mode accept mode only?
Thank you! As i understand "Execption - egress packets" are those with an error that make impossible the delivery to a valid destination. And the question now is way this packets have this errors?, but that's for packet analysis.
