Sorry forgot to comment on this...
This explains the "hang" - connections to the remove server(s) are
timing out.
Can you look at the DS access logs on a remote server during the hang
(note there is a 30 sec log buffer with the access log). Perhaps just
tail the access log, reproduce the hang (wait 30 seconds), and provide
the complete tail output.
