Periodically, the rsync command fails due to rc=23 "partial transfer due to errors". This causes a warning message in /var/log/ltm and then the file sync restarts.
The system posts a csyncd warning from rsync Command Failed, and the transfer begins again. This is a benign message that can be ignored safely.
This error can happen when the underlying file changes during the transfer. For example, if merged updates a block of the same file that rsync is transmitting.
None
Benign rsync errors are no longer logged in /var/log/ltm and instead are tracked via stats in the 'csync_stat' table.
