You didn't say whether these are the files opened sequentially during an
strace run or files open simultaneously from /proc/NNN/fd.

I'm still not able to reproduce the bug. Which version of svnserve are
you running? If you do:

 svnadmin create ...
 svnsync init ...
 svnsync sync ...

to get a fail and then you repeat
 
 svnsync sync ...

does it fail a second time? If it fails a second time that indicates a
problem with that one revision, otherwise it may be a problem that
accumulates over multiple revisions.

When you say:

 "There are 1054 file adds and 1054 property changes on those files."

are those simple adds, or are they copies? Are they all in one dir or
spread out over multiple dirs?
