Hey Joel,
There are a lot of opportunities for us to race a flow output record =E2=80=
=A6 we mark it to write out, we write it out a flow record, we mark it =
as written, with it in a number of queues, the active queue a timeout =
queue, a pending queue =E2=80=A6 that type of thing.

So I=E2=80=99m thinking that we wrote out the record, and zero'd it out =
(no metrics), and put it in a timeout queue =E2=80=A6  now, if a packet =
for it shows up, we move it to the status queue, and then update the =
record.   If somehow the queue needs to be flushed, we may not check if =
there are metrics, we just shove it to the output processor, so its =
pending, but the packets didn=E2=80=99t get tallied by the time we =
prepare the output record.

Just a guess =E2=80=A6. I=E2=80=99m going to compare with the commercial =
code later today, which is really different on this front, to see if we =
just don=E2=80=99t generate an output record in this case and return it =
to a timeout queue.

If you get records with zero src and dst pkts,  look to see if there =
were flows with the same flow ids, and lets see if there was an output =
record just seconds before this one was generated.

<div class=3D"">&nbsp; &nbsp;The Argus server occasionally generates a =
flow record with a meter DSR that is not properly parsed by the ra =
client. &nbsp;This causes the packet, byte, and appbytes counts to be =
incorrect, usually containing at least some count values from the
 previous flow record. &nbsp;Below I have included a partial dump of the =
of the problematic flow record. &nbsp;The meter DSR subtype 0x04 =
(includes app bytes) has a qualifier of 0x00. &nbsp;The meter DSR parser =
(common/argus_client.c:~2223) does not have a case to process
 a meter DSR subtype 0x04, qualifier of 0x00.</div>
