I am re-sending, because images had been removed in the original post.

I have also included more updated analytical protocol data and added 
some text I forgot.

Finally, I felt I should change the subject (to become a new thread 
instead).

It's now 2 weeks that the (same ?) problem has re-appeared on one of the 
routers (without any change on router or nfsen setup, as far as I can 
remember). "Οther" traffic and packets seems to be going nuts.

TCP and UDP seems normal, but something seems to be going wrong in 
recording "Other" (and, consequently, "Any") traffic / packets.

As an example, here is the graph of total traffic to/from ISP (1 month):

http://iweb.noa.gr/files/nfsen/nfsen-traffic-3.png

This is the out traffic only:

http://iweb.noa.gr/files/nfsen/nfsen-traffic-2.png

I am sure this graph and stats are wrong, because such traffic is beyond 
router capacity. Such traffic would overload the router (Cisco 3825) and 
exceed the link bandwidth. Moreover, it is unjustified and unreasonable.

Note how "out" Other traffic appears linearly growing over time! Also 
note that no traffic appears before Week 29, because it is so low (this 
is the true traffic!) that it is negligible when compared to recent 
traffic graphs.

(

Here are the stats for "Other" Out Traffic (to ISP) for the last 17 hours:

I strongly believe that the issue is caused by nfsen and not by exported 
data.

I am on:

    # uname -a
    Linux netvis.noa.gr 2.6.18-406.el5 #1 SMP Tue Jun 2 17:25:57 EDT
    2015 x86_64 x86_64 x86_64 GNU/Linux
    # cat /etc/redhat-release
    CentOS release 5.11 (Final)

with nfsen 1.3.6p1 and nfdump 1.6.6.

Can someone please explain what is happening and what should I do to 
correct this issue with "Other" (and "any") traffic ?

Do you think that upgrading to nfdump 1.6.13 would help?

Please help!

Thanks,
Nick
