Thanks for the nice update on the bug. This is clearly something you can reproduce and are able to trigger. However, I agree with your analysis that it could be a network configuration issue, but one that requires some deep support in order to get to the bottom of.
I suggest that you carry on debugging, and even use the bug for more debugging information. As a suggestion, you might get more visibility for deep support on rsync issues at: https://askubuntu.com/ or at an rsync specific forum. I will mark this as Incomplete for now, if you feel there is an actionable bug to fix in rsync, you can always re-open or ask on this bug. ** Changed in: rsync (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528921 Title: rsync hangs on select(5, [], [4], [], {60, 0} To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rsync/+bug/1528921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
