I've browsed through the mailing list* but I'm not certain if there is a
clear answer for the problem I'm seeing.
When checking out a project that contains a large amount of binary data
(24 GB), we are seeing the following error in the apache logs from
time-to-time (not consistent) and the checkout aborts:
Error writing base64 data. Software caused connection abort [500. #103]
Some configuration information:
- The Subversion mod_dav_svn version is 1.7.4, clients are > 1.7.4
(including 1.8 clients)
- The HTTPD info is:
Server version: Apache/2.2.15 (Unix)
Server built: Feb 13 2012 22:31:42
Server's Module Magic Number: 20051115:24

-D SERVER_CONFIG_FILE="conf/httpd.conf"
I've checked the changes list and the closest thing I see is a note in
1.7.2 that references base64, but we're beyond that version in clients
and servers.

Any tips on what to look at?
