Thank you for your feedback. @Stoo: if `rsync -vvv` is the culprit then [1] is the right upstream bug, however there are so many (mostly stale) "rsync hangs" upstream bugs [2] that I'm not sure which one is the correct one to follow-up to here. The command in the description of this report only has a single -v after all.
I think it won't be easy to make progress here without a reliable way to reproduce the issue and without the involvement of the upstream developers. What I suggest is to try to narrow the steps needed to reproduce the hang, check if it still affects the latest upstream release, and try to make the most appropriate bug move forward.

I've been able to reproduce the problem on a single subdirectory although I had to add the --debug=all flag to reproduce it on that smaller directory. Specifically, this command never completes: rsync --debug=all -avz /tmp/html2 /tmp/rsynctest/ The html2 directory is a copy of gnuradio-3.7.8.1/build/docs/doxygen/html . When I strace the command, I see this: write(1, "sender finished /tmp/html2/atsc_"..., 58sender finished /tmp/html2/atsc__interleaver_8h__incl.md5 ) = 58 write(1, "send_files(338, /tmp/html2/atsc_"..., 59send_files(338, /tmp/html2/atsc__interleaver_8h__incl.png) ) = 59 open("html2/atsc__interleaver_8h__incl.png", O_RDONLY|O_LARGEFILE) = 3 fstat64(3, {st_mode=S_IFREG|0664, st_size=264657, ...}) = 0 write(1, "html2/atsc__interleaver_8h__incl"..., 37html2/atsc__interleaver_8h__incl.png ) = 37 read(3, "\211PNG\r\n\32\n\0\0\0\rIHDR\0\0\n\253\0\0\2\233\10\6\0\0\0h\242\""..., 262144) = 262144 select(6, [5], [4], [5], {60, 0}) = 2 (in [5], out [4], left {59, 999996}) read(5, "\0\0\0\0\0\0\0\1\0\240\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\0\240\0\0\0"..., 95) = 95 write(4, "r\311\0\7\177\377\232\237\264\272e\300\300\240\316\264&\314\301\252*\37\256y\225g\373^\315j\370\350"..., 51574) = 51574 select(5, [], [4], [], {60, 0}) = 1 (out [4], left {59, 999997}) write(4, "\7\320\0\7\177\377\234|\7X\223Y\273\255c\27\25f\306\212\202\214#E\272\212t\1\225A\fU"..., 53259) = 53259 select(5, [], [4], [], {60, 0} The select command times out over and over. I get the same behavior when trying to back up my entire home directory but I don't need the --debug=all flag in that case. lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04 apt-cache policy rsync rsync: Installed: 3.1.0-2ubuntu0.1 Candidate: 3.1.0-2ubuntu0.1 Version table: *** 3.1.0-2ubuntu0.1 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main i386 Packages 500 http://security.ubuntu.com/ubuntu/ trusty-security/main i386 Packages 100 /var/lib/dpkg/status 3.1.0-2 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main i386 Packages ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: rsync 3.1.0-2ubuntu0.1 ProcVersionSignature: Ubuntu 3.13.0-74.118-generic 3.13.11-ckt30 Uname: Linux 3.13.0-74-generic i686 NonfreeKernelModules: nvidia ApportVersion: 2.14.1-0ubuntu3.19 Architecture: i386 CurrentDesktop: KDE Date: Wed Dec 23 09:44:17 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2010-09-18 (1922 days ago) InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Beta i386 (20100901.1) SourcePackage: rsync UpgradeStatus: Upgraded to trusty on 2014-12-27 (361 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rsync/+bug/1528921/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
