Package: bind9-host
Version: 1:9.7.3.dfsg-1+b1
Severity: normal
I wanted to lookup an IP address, but all I get is an error message
socket.c:4170: isc_thread_create() failed
host: isc_socketmgr_create: unexpected error
I first suspected dnsmasq being badly configured, but the same error gets
printed for 4 other DNS servers, too.
Looking with strace shows

Why is the mmap() of 1GB necessary here?
