This might be due to this bug in the checksum verification:

https://issues.apache.org/jira/browse/SVN-4722 (checksum fail during
commit when delta is 16K)

The fix was released in 1.9.9.

Also note that 1.10.3 and 1.11.0 have been released already. Those
should not be affected by this bug, so it might also be a good
opportunity to upgrade to these more recent releases ...
