Limit of 16 netflow sources per netflow "device"

I’m running several instances of 3.2.1 (I know, need
to upgrade) on FreeBSD 6.0 (I know, need to upgrade…). One of these
instances receives netflow exports from apx. 170 offices around the the US. The
offices are divided into 8 sales regions, and therefore I have 8 netflow
devices / interfaces configured on unique udp ports – one for each
The problem is there appears to be a limit of 16 senders /
exporters per netfllow device. Wait……
As I’m writing this I thought I’d check the
traffic tables to make sure I wasn’t seeing any traffic from the “missing”
networks. Sure enough, they are there! I haven’t checked for
EVERY missing one yet, but so far so good.
It appears right now the problem is only in the”
Plugins->Netflow->Statistics” page. In the “Flow
Senders” row there are only 16 senders displayed for each netflow device,
while some / most of them should have 25 or so each. I was using this
page to reconcile my configs and ensure all my office routers are indeed
exporting correctly and nTop sees them. I guess I’ll have to find a
different way to accomplish this.
If anyone has any idea’s I’d appreciate
it. Or if I need to document this better for an official “bug”
report, let me know.
