Re: Checksum mismatch creating repository?

Hi,

Using direct file:// access works with no errors, so, seems like a
http://service limit or some transfer error.

I do not think that can be any configuration of Apache, because as I said,
we installed the same subverion and make the same improt command on the same
files on Windows 7 and had no problems. We also try Visual SVN.

Perhaps some operate system configuration. Any suggestion?
