Re: Decompression of svndiff data failed

I thought this is just an dumpfile load issue. So I created a linux repo
from scratch and we've been loading it up from our Windows clients (Tortise
+ 1.4.2). Now we're seeing this:

sudo svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
svnadmin: Malformed header

sudo svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
* Verified revision 3.
* Verified revision 4.
svnadmin: Decompression of svndiff data failed

sudo /usr/bin/svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
* Verified revision 3.
* Verified revision 4.
* Verified revision 5.
* Verified revision 6.
svnadmin: Checksum mismatch while reading representation:
   expected: 21eceb49b8bea18959651e2d9e1332b4
     actual: 1230bcc2e1c99f592bc57b4c6852b069
 sudo /usr/bin/svnadmin verify .
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
* Verified revision 3.
* Verified revision 4.
svnadmin: subversion/libsvn_delta/text_delta.c:529:
svn_txdelta_apply_instructions: Assertion `tpos + op->length <=
window->tview_len' failed.

I hope to God that what we're seeing is an OS or hardware issue. Anyone
have any ideas?
