We've found an (apparently) simpler case of what looks like the same error:
$ svn ls https://domain.example/dir1/PROJECT/trunk/README README $ svn cat https://domain.example/dir1/PROJECT/trunk/README svn: '/!svn/bc/23694/dir1/PROJECT/trunk/README' path not found I don't see any command line options, or options for mod_dav_svn, to log more information as it runs. Would rebuilding subversion with --enable-debug and --enable-maintainer-mode provide more information to see what's going on here? Or is this a simple case of a corrupted repository? In which case, any suggestions on how to proceed? It's not too late to re-run cvs2svn and recreate the changes we made since last time, if cvs2svn was what corrupted it and we can fix that before running it again. Thanks for any help on how to proceed, Dan
