[ILUG] rsync over ssh problem

[kevin]

Part of our backup routine is a cron job that runs rsync over ssh to an
offsite computer every night. Recently I have noticed that it fails
about 1/2 of the time, not always and a failed rysnc one night might
work fine the next night.

The error we get is:

Write failed: Broken pipe
rsync: connection unexpectedly closed (13729658 bytes received so far)
[receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(601)
[receiver=3.0.7]
rsync: connection unexpectedly closed (783 bytes received so far)
[generator]
rsync error: unexplained error (code 255) at io.c(601) [generator=3.0.7]

I have the "KeepAlive Yes" option in the sshd_config file

rsync options used in the batch file are:

rsync -e ssh -avzxHS --numeric-ids --del --delete-excluded
--exclude-from "/home/cybercolloids/exclusions.txt" --exclude ".gvfs"

Looking at the log file the only thing that looks odd is that the
connection fails when transferring large image files - a few Mb

Any ideas?

Thanks

Kevin.
