Hi,
this is caused by hard-wired limit for number of flow exporters and
maybe by bug in nfdump. In easy words, this will occur when you send
flows from many sources to a single nfcapd process. It seems, that you
must send flow data from more than 256 routers but it is not true. If
you restart nfcapd and then let nfdump to analyse data before and after
the restart, then routers before and after the restart are treated as
different routers, so the number of analysed routers will double! So if
you analyse time interval where you restarted nfcapd multiple times and
have bigger number of routers, than you can easily reach this limit. You
can fix it by increasing constant
#define MAX_EXPORTERS 256
in exporter.c file. But I am not sure, whether the increasing of this
value can influence something in bad way. The testing is needed. Maybe
Peter can say, if I am right.
Regards,
Jan
