We've been seeing errors like this when trying to compare a tagged tree to our trunk. I've tried to recreate with a small repository, but haven't been able to.
I'd appreciate suggestions on where I should look next to figure this out. svn diff \ https://domain.example.com/dir1/PROJECT/tags/PROJECT_3_1_154 \ https://domain.example.com/dir1/PROJECT/trunk svn: '/!svn/bc/23689/dir1/PROJECT/tags/PROJECT_3_1_154/src/utils/Filename.java' path not found svn: Error reading spooled REPORT request response Version: subversion 1.6.6 Server: Apache httpd 2.2.14 with mod_dav_svn, mod_authz_svn Repository format: fsfs Platform: linux The repository was created from a large CVS repository using cvs2svn, where the tag already existed. (The commit message confirms that cvs2svn did the svn commit creating it.) Thanks, Dan
