I have here a script with which I was able to reproduce this issue on Debian 7, Debian 9, Ubuntu 17.04 for rsync 3.1.2 (Ubuntu 17.04 apt repo) and 3.1.3 (built from source).
https://pastebin.com/ctzJJGwt It essentially creates a folder with 11.5k files of size 600KB and 10 files of size 200MB, however I think those 10 files are not necessary to trigger the fault. Using this command rsync -avvvz --delete source_dir target_dir I've also built rsync 3.0.9 which runs this command fine. I suppose at this point it's a rsync issue, I will submit this to the rsync bug tracker. For now using rsync 3.0.9 as a workaround is fine for me. I appreciate any feedback if anyone else is able to reproduce this issue using the supplied script. -- 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
