Commit failure when doing concurrent commits: "the specified activity does not exist"

Hello guys, I'm running the following configuration: OS:  Ubuntu 8.04 (Hardy Heron) svn: 1.4.6dfsg1-2ubuntu1.3 apache2: 2.2.8-1ubuntu0.22 apache2-mpm-prefork: 2.2.8-1ubuntu0.22 And experiencing the following problem: When performing simultaneous commits from 5 different stations, some commits fail with the following messages (taken from the apache error log): [Wed Dec 14 09:59:20 2011] [error] [client 10.46.1.21] Could not CHECKOUT resource /cp1-svn/!svn/bln/17472.  [409, #0] [Wed Dec 14 09:59:20 2011] [error] [client 10.46.1.21] The specified activity does not exist.  [409, #190002] I've been browsing through the 1.4.6 subversion sources and noticed that this error message is given when apr_dbm_open or apr_dbm_fetch fail for any reason (look in mod_dav_svn/activity.c  --> const char *dav_svn_get_txn) so I would assume this is caused by concurrency issues in Berkley DB or in APR... (though this is just an assumption...) Regards
