Hi Maurizio,
Is it possible the interface used for export of NetFlow packets became
unavailable at that time (link down, maintenance, hardware issue, etc.)?
yes, this was by sure the problem
Such kind of happening would be the linking pin among the two, otherwise
unrelated, messages.
Should the export socket become unavailable for some reason, nfprobe
would not currently re-stablish it - even just as a matter of a try,
which IMHO is good idea instead and would be matter of a few lines of
code.
I'm not sure I understand what you said... are you saying you're taking
this in as a feature request?
thanks,
Maurizio
If this rings a bell - do you have a way to reproduce the issue so to
test we are shooting right?
Cheers,
Paolo

Hi,
I'm experiencing that nfprobe is stopping exporting flows after a while
(a few days) on some of my system. It does not crash, but it stops
exporting flows.
Before it started writing to syslog the message " unable to export
flows" I saw these two lines:
<1b>Jan 8 01:40:49 santiago zebra[5580]: netlink_interface_addr can't
find interface by index 71
<1b>Jan 8 01:40:49 santiago zebra[5580]: netlink-listen filter function
error

<1c>Jan 8 01:40:57 santiago pmacctd[21090]: WARN ( 1/nfprobe ): Unable

<1c>Jan 8 01:40:59 santiago pmacctd[21090]: WARN ( 1/nfprobe ): Unable
to export flows.
<1c>Jan 8 01:41:01 santiago pmacctd[21090]: WARN ( 1/nfprobe ): Unable
to export flows.
......
Any idea is these errors are related?
Thanks,
Maurizio
