Fluentd process is stuck at `Socket.pack_sockaddr_in` on shutdown.

gistfile1.md

Fluentd does not die sometimes (stuck on shutdown).

I dumped the ruby backtrace using sigdump. The result is attached at gistfile2.txt. Below is a part of it.

  Thread #<Thread:0x00000001df50d8> status=sleep priority=0
      /usr/lib64/fluent/ruby/lib/ruby/gems/1.9.1/gems/fluentd-0.10.43/lib/fluent/plugin/out_forward.rb:118:in `shutdown'
      /usr/lib64/fluent/ruby/lib/ruby/gems/1.9.1/gems/fluent-plugin-keep-forward-0.1.2/lib/fluent/plugin/out_keep_forward.rb:34:in `shutdown'
      /usr/lib64/fluent/ruby/lib/ruby/gems/1.9.1/gems/fluentd-0.10.43/lib/fluent/plugin/out_copy.rb:56:in `block in shutdown'

This tell us that Fluentd is stuck at /usr/lib64/fluent/ruby/lib/ruby/gems/1.9.1/gems/fluentd-0.10.43/lib/fluent/plugin/out_forward.rb:286. The code around the line is as followings:

275     def on_timer
276       return if @finished
277       @nodes.each {|n|
278         if n.tick
279           rebuild_weight_array
280         end
281         begin
282           #log.trace "sending heartbeat #{n.host}:#{n.port} on #{@heartbeat_type}"
283           if @heartbeat_type == :tcp
284             send_heartbeat_tcp(n)
285           else
286             @usock.send "\0", 0, Socket.pack_sockaddr_in(n.port, n.resolved_host)
287           end
288         rescue Errno::EAGAIN, Errno::EWOULDBLOCK, Errno::EINTR
289           # TODO log
290           log.debug "failed to send heartbeat packet to #{n.host}:#{n.port}", :error=>$!.to_s
291         end
292       }
293     end

This tells that Fluentd gets stuck at Socket.pack_sockaddr_in.

I also attached the result of gdb backtrace at the bottom. Below is backtrace of around Socket.pack_sockaddr_in.
