Robert,
  Perhaps unrelated, but I had a hang-at-end situation which at least
  sounds similar.  I tried to use a 3.0.x binary which had been compiled
  on a PPC, on an intel-mini;  it seemed to hang at the end.
  Recompiled on the intel-mini, no problem since then.

Hi All,
My wrapper application for rsync 3.0.2 on osx has been working smoothly except for reports of it hanging on the last file of the transfer to a local firewire drive. We seem to have solved the mystery of the slow transfers but now, every four or five runs, it hangs at the last file to transfer and refuses to quit. Activity Monitor shows three rsync processes all at 0%CPU at that point (and virtual memory allocated of 3.74GB, 2.6GB and 2.6GB!). The last file incidentally is /usr/standalone/bootx.xcoff

My friend is using the standard options

-aHAXN --fileflags --force-change   --stats -v --progress

on an Intel mac copying his system of 100GB, or 1 million files, to the external drive. As I said, it works well and always copies all of the files perfectly. When the hang occurs, the output shows nothing unusual - it just stops at the last file transferred and does not proceed to shut itself off. We havn't managed to run with -vvv when this happens but will try to catch it with that now. I should also mention that rsync is launched via do shell script and the output sent to a log file in /tmp which the app reads progress from...

I googled around and found references to an rsync end hang that said the child process wasn't getting the quit signal from parent rsync.... (on rsync 2.5.5)

Don't know if that is relevant at all...

Any thoughts, anyone?

thanks so much for this great tool!
