Hi Satadru
I have got quick response from Burton that is one of the upstream developers
of ntop.
Unfortunatly the gdb trace did not get anything...
But he ask you to run ntop with "-t 4" or higher so if you could do
that it would be nice. See below what Burton writes for more information
about this.
Please reply directly to Burton, me and the bug number. Reply to all
would give that result.
Regards,
// Ola
