The following is an excerpt from my Apache log and shows ALL hits made
on the
Subversion repository between two failures. It is the shortest period
I've found
between errors, and includes only 29 successful accesses:

Another thing to note is that none of the above should cause any changes to
the repository.
I believe you are right in that it is a locking problem, as the svnadmin
process
will lock/wait indefinately if I try to run the recovery without
shutting down
Apache.
Yours,
Morten
