I was experiencing problems with authentication (using HTTP Digest Auth+SSL) on our SVN server. It seems it has been reported a few years ago (see http://subversion.tigris.org/ds/viewMessage.do?dsForumId=1065&dsMessageId=911173), but I was not able to find a solution anywhere. The problem occured most often when merging, sometimes when checking out/in or updating. Trying to work around another problem (apache leaking memory, see https://bugs.launchpad.net/ubuntu/+source/subversion/+bug/273859), I set 'SVNAllowBulkUpdates Off' which caused the authentication problem to occur a lot more frequently. Finally it seems both my problems are gone after switching from mpm-worker to mpm-prefork, with 'SVNAllowBulkUpdates Off'.
This info might be useful for other users experiencing the same problem and give a hint that the authentication problem seems to be related to threading issues.
