Hi Luca,
I tried valgrind - but there is so much output I can't really figure out
what is happening.
I did try compiling only Redis.cpp with -O2 and that fixed my problem
on the CentOS 6.4 boxes. The only difference between 6634 when I started
seeing the problem are shown below.
Also as a side note I took my compiled ntopng binary from my F14 system
compiled with gcc-c++-4.5.1-4.fc14.i686 and it worked on the CentOS 6.4 box.
The compiler on CentOS 6.4 is gcc-c++-4.4.7-3.el6.i686 which is the latest
available on CentOS 6.4.
Also I compiled ntopng on F12 with gcc-c++-4.4.4-10.fc12.x86_64 and it worked
fine.
So it seems there is something about the CentOS 6.4 gcc version that is causing
the
problem when compiled without optimization.

please run ntopng with valgrind (and without -O2) to figure out that errors you
experience (this as everything works for me)

Hi Luca,
Don't know what to think about this but
I add -O2 to the CPPFLAGS and now I don't
get any errors!
Go figure.

Hi Luca,
I am still fighting this problem.
Another data point is if the
host list shows a mac address as "local" it works OK.
It is only when the host list show an ip as "local" that
I get the following error. I went thru the host_details.lua
script and made checks for nil but it seems like everything
is nil.
In what module is the data stored?
I have been trying to understand the architecture of ntopng
but so far have been very successful.
Thanks,
Steve

In case you are not aware I am seeing the following when trying to select a
