RE: Broken repository. svnadmin verify and dump report a checksum mismatch.

From: John Savage <JSavage_at_data-mate.com>

We have a number of developers that use dual CPU windows PCs for their WCs
and there are no problems. However my issue wasn't client side, it was with
the server running on a dual CPU system.

Has anyone had any experience hosting svnserve and the repository on a dual
CPU RAID 1 system (be it windows or otherwise)?

My experience was consistent reproducible corruption of the repository on
the SMP system, which went away only when I moved the repository to a single
CPU server.

Thanks,
John

        Our SVN repository is on a single-CPU Linux server: many developers
work on
their WC's on a dual 1.3Ghz Linux server. I would suggest that, if it is a
problem with an SMP environment, it may be more specifically a Windows SMP
problem. More information:

developer machine
        CPU: dual 1.3 Ghz PIII
        OS: Debian 3.1 (kernel 2.6.11.10)
