I strongly suspect there is something wrong with your machine (memory going bad?). The repository is nothing more than a dump/load from the greek tree. After a dump/load the repository has the UUID set. No other modifications happen to the repo and the only access to the repository via the server is the update command that's failing. That rules out a problem with caching because the cache should be entirely cold for this repository when the update command runs. The error you're getting is: svn: E160004: Corrupt node-revision '0.0.r1/4198' svn: E160004: Missing id field in node-rev The closest id in the repository is this: 0.0.r1/4206 The number after the slash is the offset which is stored in the private portion of the svn_fs_id_t. The offset is stored as a apr_off_t (i.e. not a string but a integer). Looking at the offsets in binary yields (leading zeros ommitted): 4206 = 1 0000 0110 1110 4198 = 1 0000 0110 0110 Note that they are off by exactly bit. A memory issue would probably be very hard to reproduce. So this seems to fit with the issues you've been having. Combine that with the fact that you've been having unreproducible test failures in other places with this setup. I have to conclude you have issues with your memory. I'd suggest running memtest86 on the machine.
