Here's a new debug session with the above requested information:
http://www.brixandersen.dk/tmp/zfs-rsync-debug.2.txt
As you can see, there were a couple of LORs before I entered the
debugger. At least one of these (the last one) appeared when trying to
list the files in one of the zfs filesystems, where rsync was hanging.
This is with RELENG_7 from Thu Oct 25 14:30:37 CEST 2007.
Regards,
Brix
