rsync - Feb 2002 - Solaris 2.7 error in file IO (code 11) at main.c(883)

I'm updating to version 2.5.2 on a Solaris 2.7 (and 2.6) system.

The rsync process seems to run but finishes with the following:

wrote 91830 bytes  read 4589600 bytes  105200.67 bytes/sec
total size is 127959731  speedup is 27.33
rsync error: error in file IO (code 11) at main.c(883)

I've tried the binary downloaded version and recompiled myself from the
source.

Is the error message an indication that the process didn't correctly
sync the systems or that some closing cleanup was incorrect?

Thanks
