The server error suggests that at least one of the files that make up the transaction is missing from disk when the MERGE is attempted. That's odd, it is not a commonly seen error. Even more odd is that you show "svnadmin rmtxns" succeeding. This is odd, very odd, because when a MERGE fails the server code in mod_dav_svn reacts by removing the transaction from disk. In addition, when the client gets the failed MERGE repsonse it also reacts and sends a DELETE to remove the transaction from disk; this DELETE usually fails with 404: [dav:error] [pid 13161:tid 140441001391872] [client ::1:44218] Could not fetch resource information. [404, #0] [dav:error] [pid 13161:tid 140441001391872] [client ::1:44218] Named transaction doesn't exist. [404, #175002] Do you see the DELETE in the log after the failed MERGE? Was there an error? After a failed MERGE an attempt to run "svnadmin rmtxns" manually would normally fail with: E160007: No such transaction '463-e8' but your attempt succeeded so at least some of the transaction was present on disk. So it looks like several strange things have happened: - one of the files on disk that make up the transaction is missing causing the MERGE to fail - both automatic attempts to delete the transaction on disk have failed causing the transaction to persist on disk - whatever caused the transaction to persist on disk doesn't prevent "svnadmin rmtxns" from working The "_1bqk" implies that this transaction affects over 60,000 nodes, this is large but Subversion should handle it.
