FW: rsync hanging after working reliably for years on one of my shares
Thanks for the suggestions - I have done my best to follow them.
I inserted the debug shim script and changed the rsync executable in rsync so
that it called that instead, and got the same results. Here is the tail from
that:

Also, I did do a manual rsync of that last file using similar options, and it
worked fine.
The share I am backing up contains 3 folders, an index.html and an htaccess
file. No packages changed on the backup or target server in the prior 3 months.
No files have changed on the target server of note in the last month (just some
xml site layout files spit out by wordpress and the nightly mysql dump). No
drastic changes in file size. Stumped...
Adding the /var/www share back in...hangs again...
Ideas?

Subject: rsync hanging after working reliably for years on one of my shares
Howdy all,
I'm using rsync in conjunction with backuppc and have been backing up this
share without incident for almost 3 years and it has decided to go and hang on
me. Other shares on the same machine sync fine with identical settings, and
nothing has changed on the backup end other than some routine dist-upgrades to
keep update on security patches. I checked the apt cache and no rsync related
dpkgs seemed to be hanging around in there so...
Checked files with recent ctimes and mtimes, nothing funny looking there like
recursive links.
Log excerpt attached beneath. I think alphabetically xmlrpc.php may be the last
file in the share, is it coincidence it hangs right after? Thoughts? Ideas?
Unfounded speculation? Blatant slander? Anything? Just about out of ideas on my
end. I've got a dozen or so other hosts that are happily syncing away and
passing all their unit tests but this one has greeted me the last 5 or 6 days
with a sad face and I don't seem to be making any progress. Any ideas at
all? Again, log snippet underneath. Let me know if this is a backuppc issue and
I am barking up the wrong tree, but there is definitely an rsync process sitting
out there indefinitely long.
