Googling for svnsync path "not present" also finds the following threads:




From the CHANGES file:
Version 1.4.4
    * fixed: svnsync cannot sync unreadable modified dir copies (issue #2705)

Version 1.4.6
    * fixed: svnsync ignores '--config-dir' (r27056)

Version 1.5.0
    * 'svnsync' had bug with replaced+modified rev over serf (issue #2904)
    * 'svnsync --config-dir' sometimes ignored, thus tunnel agent bug (r27056)

Question: are you mirroring the whole repository? Are all paths in it
readable by the svnsync user?

I suggest trying the following:
(make a hotcopy of your mirror repository before that, for reference)
1. Try syncing with the latest revision of subversion client (1.5.1).

If it is able to resume from the revision where the 1.4.3 client fails, then
you are bitten by a bug that is already fixed.

If it fails, there is some bug in the current code.

Needs to be mentioned:
The 1.5.x subversion can be installed on some other computer. There
is no need to upgrade your server, unless you are using the
file:// protocol to access it.

2. Create a dump file for a single revision - the one that svnsync fails
to process (85224) and try to load it into the mirror.

There should be something in that revision, that triggers the issue.

If it succeeds, you can update the properties on revision 0 to reflect the
change. Use "--revprop -r 0" arguments, e.g.
svn proplist --revprop -r 0 repository-url
