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!
Rob D
