the mail with the whole strace is kept because of the attach but i can see this
sendto(3, "<30>Nov 28 16:17:46 pdns[167106]"..., 57, MSG_NOSIGNAL, NULL, 0) = 57

PDNSException while filling the zone cache: Exception caught when sending:

) = 134
it looks like the socket is being closed when pdns is trying to send a new
message (the getAllDomains)?
