>Description:
After updating system from version 5.4 up to version 6.0 my collector began to inform on losses of flows. Probably, a problem in discrepancy of sequence number (flow_seq in netflow_v5_header).

myflowcollector: lost 7650 flow records for router vpn3 !
>How-To-Repeat:
Use ng_netflow and use a netflow collector with the control of a sequence number.
