I can't tell you specifically why this happened, but I'm willing to
bet that the most relevant contributing factor is two B's with a D
sandwiched in the middle, and that FSFS repositories are probably the
more-stable platform you're looking for. I've been on the list half a
year, and I long ago lost count of the number of BDB-related
repository problems I've read about, whereby access to a repository
was (usually temporarily, but sometimes permanently) lost through no
fault of the administrator. Conversely, I can't recall a single
similar post about FSFS in that time.
The Subversion team will be quick to come to the rescue of BDB's
reputation and assure you that there is no problem with BDB per se,
it's just the way Subversion is using it. These details were,
however, immaterial to me when I chose to use FSFS for my company's
repository; all I cared about was the reliability. Our FSFS
repository is used daily by 5-10 developers over Apache2, working on
both separate and joint projects. The repository is 800MB in 2600
revisions, and we haven't had any problems yet.
As of Subversion 1.2, FSFS is the default, which says to me that the
Subversion team feels it's solid, and I would tend to agree. I
encourage you to upgrade to Subversion 1.2 and try it. (1.2 has a
slightly different FSFS storage mechanism than 1.1 which is supposed
to make it a bit faster.)
