Repository getting corrupted

We have subversion server,
Version: 1.4.4
Apache: 2.2.8
mod_svn 1.5
We are also using web dav.

Past history:
Initially from user we come to know they are getting truncated error while commit/update or full checkout.

Upon verification (svnadmin verify) we come to know three repo's are corrupted. So we rectified the issue by rebuild repo's (export/import) and removed the corrupted revision.

The error we are getting that is:
"Invalid diff stream: insn 1249 has non-positive length".

But later, one of the corrected repo again got corrupted. This time error is,
svnadmin: Decompression of svndiff data failed.

This time I try to resolve the issue as discussed in, http://www.mayurjoba%e2%80%8bnputra.com/index.php%e2%80%8b/2008/07/20/svnadmin%e2%80%8b-decompression-of-sv%e2%80%8bndiff-data-failed-an%e2%80%8bd-fsfsverifypy/.

But this does not resolve the issue, so I did not have the option but to rectify from same process, export/import and remove corrupted repo.

We are still getting repository corrupted with following example errors:

svnadmin: Checksum mismatch while reading representation:
   expected: 48d8d49ed9d6fb53f04ea778c4032289
     actual: 7aaa667413bcc040c21cc93952dc9840

svnadmin: Decompression of svndiff data failed

Please note this is now happening on regular basis. In every gap two/three days on of the repository is getting corrupted. We have another similar environment this issue is not getting replicated there.

Let me know any other information needed.

Any help is really appreciated. As we are still not aware of root cause.
