Hi all:

I have been running backuppc on a host for a few months now without
issues. All of a sudden, I have been getting hung backups. If I use
lsof on the rsync processes running on the client, I see the running
process, but without a file descriptor 3. I.E. it's running and
listening, but it is not reading any file.

The log file lists:

2009-01-01 23:00:01 incr backup started back to 2008-12-26 23:00:01 (backup 
#195) for directory /etc
2009-01-02 16:07:36 Aborting backup up after signal INT
2009-01-02 16:07:37 Got fatal error during xfer (aborted by user (signal=INT))
2009-01-02 16:07:53 full backup started for directory /etc (baseline backup 
#198)
2009-01-02 16:29:59 Aborting backup up after signal PIPE
2009-01-02 16:30:00 Got fatal error during xfer (aborted by signal=PIPE)
2009-01-02 16:30:00 Saved partial dump 199
2009-01-02 16:30:16 full backup started for directory /etc; updating partial 
#199
2009-01-02 16:30:24 full backup started for directory /var/bak; updating 
partial #199
2009-01-02 16:30:27 full backup started for directory /var/log; updating 
partial #199

The sigpipe was due to my killing the rsync process after seeing it
start up, transfer a couple of files (determined by watching file
descriptor 3 of the rsync process) and then just hang with no
activity. Given that it should only take a few minutes (at worst) to
process the directory I was pretty sure it wouldn't come back.

Note what happened on the next pass. The partially saved full dump was
used as the baseline and things completed without any issue.

So my supposition is that something was wrong with the prior
incrementals that was hanging the client.

Does anybody know of a mechanism by which this could occur in
backuppc?

More importantly, if this happens again what can info can I provide so
the the developers can debug and fix it?
