Public bug reported:
When I try to load system-config-printer, it takes tens of seconds to
load. Any interactions take many more seconds, to the point that this
utility is unusable.
When I strace initial loading, here is what I get:
socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 16
setsockopt(16, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
setsockopt(16, SOL_SOCKET, SO_REUSEPORT, [1], 4) = 0
setsockopt(16, SOL_TCP, TCP_NODELAY, [1], 4) = 0
fcntl(16, F_SETFD, FD_CLOEXEC) = 0
fcntl(16, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(16, F_SETFL, O_RDWR|O_NONBLOCK) = 0
connect(16, {sa_family=AF_INET6, sin6_port=htons(631), inet_pton(AF_INET6,
"::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EINPROGRESS
(Operation now in progress)
fcntl(16, F_SETFL, O_RDWR) = 0
poll([{fd=16, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=16, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=16, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
poll([{fd=16, events=POLLIN|POLLOUT}], 1, 250) = 0 (Timeout)
...
IPv6 is disabled on my system:
ezyang@sabre:~$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1
This pattern seems to repeat whenever the interface hangs.
