segfault at 000000000311c000 rip 000000000040fb46 rsp 0000007fbffff830 error 4

[Carter Bullard]

Hey Gunnar,
The gdb() commands of interest are:

    (gdb) where

ArgusLoadList() is the routine that passes flow record status reports  
from the
packet processing engine to the output processor.  This definitely  
shouldn't
have a problem, so it will be interesting to figure out what the  
problem maybe.

Are you running with threads enabled?  (is there a ./.threads file in  
your root directory?)
