>How-To-Repeat:
In my configuration file prescribed 5 interfaces are likely to experience a problem when using a large number of interfaces.
>Fix:
Most likely reason is the small length of line available to store the names of the interface in the 244 line config.c
I believe that the line
tmpPtr-> name = (char *) malloc (sizeof (char) * strlen (token));
should be replaced by the
tmpPtr-> name = (char *) malloc (sizeof (char) * (strlen (token) + 1));
