Problems with rsync -e ssh

[David Rippel]

I'm doing the following from a linux box to a solaris box:

rsync_options="-aPvrz --progress --stats --delete --delete-after"
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/docs/ /export/export/www/current/www
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/was/ /export/export/www/current/www
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/soe/ /export/export/www/current/www
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/cgi-bin/ /export/export/www/current/www
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/CustomTags/ /export/export/www/current/www
rsync $rsync_options -e ssh root at 207.156.7.100:/usr2/servlet/ /export/export/www/current/www

The initial rsync works as expected. Subsequent rsyncs result in files that have not changed still being transferred. I've tried using --size-only with no luck. I've checked the md5 sums and verified the files are truly the same.

Am I missing something?
