Here is a strace during the problem:
recvmsg(4, {msg_name(16)={sa_family=AF_INET, sin_port=htons(50141),
sin_addr=inet_addr("127.0.0.1")},
msg_iov(1)=[{"z\320\1\0\0\1\0\0\0\0\0\0\4push\10services\7mozil"..., 4096}],
msg_controllen=0, msg_flags=0}, 0) = 43
sendto(11, "3\202\1\0\0\1\0\0\0\0\0\0\4push\10services\7mozil"..., 43, 0,
{sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("8.8.8.8")}, 16) =
-1 ENODEV (No such device)
sendto(11, "3\202\1\0\0\1\0\0\0\0\0\0\4push\10services\7mozil"..., 43, 0,
{sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("8.8.4.4")}, 16) =
-1 ENODEV (No such device)
FD 11 is:
dnsmasq 21412 nobody 11u IPv4 1438842 0t0 UDP *:38279
So, it doesn't really seem to be related to the original bug
report. Sorry for the noise, I'll dig more and open another bug report
if needed.
