I run PowerDNS (/etc/init.d/pdns monitor), it installed on SunOS 5.8
SPARC. If I query from my PC (client), PDNS reply correctly with some
DNSs .Next, the error, "Bus Error" , occured and PDNS stops.
I don't compile the PDNS with option: enable-recursor but I enable
this option in Configuration file (pdns.conf). I use gmysql and geo as
backend. Following is the detail of pdns.conf:
