Ok, I have tested this little bit more:

With SDBM, system finished over 8K commits without hitch.

With BDB 4.0, I got these two errors:
   svn: Commit failed (details follow):
   svn: MERGE request failed on '/stress/repostress/trunk'
   svn: Reference to non-existent node '0.0.r-1/-1' in filesystem
   '/svnrel/tmp/repostress/db'
and
   svn: Commit failed (details follow):
   svn: The specified activity does not exist.

With BDB 4.2 or 4.3, I got only this one:
   svn: Commit failed (details follow):
   svn: The specified activity does not exist.

With GDBM (1.8.3), I got these two:
   svn: Commit failed (details follow):
   svn: Could not open activities database
and
   svn: Commit failed (details follow):
   svn: The specified activity does not exist.

So it looks like that here only SDBM works as activity backend. With
anything else, first activity error pops up during the 10-20 first
commit. However, this very same system (chroot) compiles and runs
nightly regression tests, so it can't be completely nuts.

Where should I look next, to apr-util, these databases, or mod_dav_svn?
Used apr-util is 0.9.6.

BR, Jani
