Hi

I use rsync to make backups of large filesystems - totalling many
Terabytes and 100 millions of files.  The following error occurs often
enough to become a problem.  You will note, that I am using 2.6.6,
previously I used 2.6.2 which had the same issues.  The OS is solaris
5.8.  I am using the delete backup feature of rsync and it seems to me
that somehow, there is a connection breakdown between the sender and
receiver, during the 'delete backup' phase in the beginning. 
Restarting the rsync 2 or 3 times eventually leads to a successful run.



Today, I added the --delete-during switch and there appears to be an
improvement in that all the rsync jobs have run much longer without
issue.  This in some way strengthens the idea that the problem related
to a loss of communication during the backup/delete phase.



If anyone has any ideas or suggestions I would be most appreciative

thanks

Mark
