I was getting that error last month:

http://svn.haxx.se/dev/archive-2011-03/0745.shtml

What I find is that the problem sometimes appears and sometimes does
not. It's not predictable either, repeating a failed export/checkout
will sometimes work and sometimes fail at a different place. That is
the case when I try that neon URL:

svn: E200014: Checksum mismatch for 'subversion/tests/xx/src/ne_openssl.c':
   expected: 3bd789b372ca14793e8ac228cdf43a15
     actual: be72d4221d805da2484b1cd0182b9049

svn: E200014: Checksum mismatch for 'subversion/tests/xx/src/ne_ssl.h':
   expected: 6fbb6c5dda02229623c887a9a08b1533
     actual: 4f0c8e04845b70ebf1e88adbb780a2f0

I suspect the pool/memory handling in serf or libsvn_ra_serf, but I'm
not certain.
