file sizes different even after successful rsync

[Kulkarni, Jaydeep]

Is it even remotely possible that after a successful rsync, the file sizes on both ends are different ???
 
We use rsync extensively to distribute our builds across all our development sites. Here is how our rsync process works
 
1. SiteA creates a build #1
2. SiteB rsync's build #1
3. SiteA creates a build #2
4. SiteB rsync's build #2 using contents of build #01 (i.e. we rsync build #02 into #01 directory and then call #01 as #02) The idea being, rsync will be able to figure out which files have changed between build #01 and build #02 and X'fer only the changed files.
 
However, step 4 above is not doing correct things. Rsync detects that the files are different but doesn't X'fer but doesn't sync it. Following is a snapshot of the log. Notice the lines in "red" below. Rsync correctly detects that these CD image files need to be synced but doesn't actually X'fer much bytes. The command completes successfully but the sizes don't match.
 
Have any of you seen this problem before? I am using Redhat 8.0 at rsync server and Solaris 8 as rsync client. At both ends I am using rsync 2.5.6 protocol version 26
 
Thanks in advance for your help.
