Can you recompile the software with following changes: edit Makefile and make sure your OPTFLAGS are '-O0 -g'
before starting, run 'ulimit -c unlimited' Then start it normally, and hope it crashes. It should produce a core file. You can see where it crashed by typing 'gdb /path/to/binary /path/to/core' Aki Tuomi On Tue, May 28, 2013 at 01:37:36PM +0800, jacky wu wrote: > $ ./configure && make install > $ sudo /usr/sbin/pdns_recursor --daemon=no > May 28 13:35:52 PowerDNS recursor 3.5.1 (C) 2001-2013 PowerDNS.COM BV (May > 26 2013, 22:54:09, gcc 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.27)) > starting up > May 28 13:35:52 PowerDNS comes with ABSOLUTELY NO WARRANTY.
