Last night I recompiled httpd and mod_dav with debugging enabled, and ran
httpd in gdb with arguments "-X -DSSL -f /var/www/conf/httpd.conf". I set a
breakpoint in sdbm_store, which was the routing that was failing with errno
= EINVAL. After a little digging, I found the following:

mod_dav constructs a dbm key based (at least in part) on the file name being
locked. However, the file name used to construct the key was always the
empty string. Looks a lot like there is a bug in mod_dav.

I'm relatively new to the DAV and OpenBSD communities, and am wondering if
it makes more sense if I take this up on either the port-bugs or the dav-dev
list.

Thx,
Nick
