Hi Steve,
I do have avail of a i686-based VM. I can't say everything is tested on
i686 but i tend to check every now and then that nothing fundamental is
broken. I took the example config you used, compiled master code with
the same config switches as you did (essentially --enable-ndpi) and had
no joy reproducing the issue.
You could send me privately your capture and i may try with that one
(although i am not highly positive it will be a successful test); or you
could arrange me access to your box to read the pcap. Let me know.

Hi Paolo,
I have compiled master with nDPI on both 32bit and 64bit CentOS 6
systems. The 64 bit pmacctd seems
to work fine. But I get bogus byte counts when I run the 32bit version
against the same pcap file.
Just wondered if you have done any testing on 32bit intel system with
the above combination.
below is the output when using 32bit pmacctd - first the pmacctd
invocation then the nfacctd output
