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

   Partial hex dump of the flow record:
