[nsd-users] NSD 4.3.2rc1 pre-release + warning: process terminated with status 11

[Jeroen Koekkoek]

Hi Andreas,

You may want to set (export) CFLAGS="-g -O0" before running configure
and then start NSD through valgrind (valgrind nsd ...). The output will
(hopefully) show where NSD accesses already freed or uninitialized
memory as status 11 indicates a segmentation fault.

Cheers,
Jeroen
