Can't install the latest dev at this time, but I reran the rsync again  
and have the following to report.  Below is a list of the processes:

[iepsiu001] / # ps -ef|grep rsync
     root  9482  9481  0 09:22:23 pts/2    0:00 /opt/csw/bin/rsync -av  
--delete /rsync/ieeprodhome/ECF/ /rsync/ieeprodhome2/ECF
     root  9481 23946  3 09:22:23 pts/2    1:18 /opt/csw/bin/rsync -av  
--delete /rsync/ieeprodhome/ECF/ /rsync/ieeprodhome2/ECF
     root 14676 28952  0 09:28:18 pts/3    0:00 grep rsync
     root  9494  9482  3 09:22:23 pts/2    1:22 /opt/csw/bin/rsync -av  
--delete /rsync/ieeprodhome/ECF/ /rsync/ieeprodhome2/ECF

I won't flood the list with the last screenful of outputs of the three  
processes, so I'll put them on a web server and let you take a look at  

They are all here:
