Hello list, 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. Cheers, Kai PS. I'm not subscribed to the list, please CC me in responses or mail me in case I can help with more detailed info.
