it could simply be that you're exceeding the maximum filesize limit of
your Apache.
LARGE_FILE support might be needed but it maybe also be a problem in
mod_dav_svn related to BDB.
I know that Midnight Commander can crash if you try to transfer a
several gigs big file over smbfs but works if you do it with a CIFS
mounted SMB share.
if you're able to use Apache 2.2 with APR-1.2.x try this.
as a first test try to download/upload a 3GiB file from/to Apache and
see if that also breaks Apache. if this is the case you will have to
upgrade to Apache 2.2 anyway.
