------------------------------------------------------------
Issue SVN-4157 is what looks like the same crash with the 2.4 event MPM and BDB
and it's easy to provoke by running the testsuite. I've never seen worker crash
when running the testsuite, perhaps it is something to do with the way the
worker MPM is configures in the config file? Perhaps the testsuite sets up
worker so that the threads get used in a way that doesn't trigger the bug?

> I have seen reports of this in email, and experienced it myself, but I cannot
> find any bug report for this in the bug tracking system.
> The issue is that with mpm_worker, mod_dav_svn will cause the apache process
> it
> is in to core dump. This only happens when the frequency of SVN requests
> increases (ie. occasional usage does not cause this - however when doing
> something like a repository diff scan (ie. repeated requests to get all diffs
> to
> build a diff database for something like a subversion front-end like FishEye)
> will trigger it every time).
> It has been previously reported here:
> http://svn.haxx.se/users/archive-2006-02/1317.shtml
> And is also listed as a bug on the apache issue tracker (though it is more
> likely a mod_dav_svn bug than an apache bug):
> http://issues.apache.org/bugzilla/show_bug.cgi?id=42262
> The latter link includes a stack trace (Thread 9 is interesting), but
> unfortunately I did not have subversion compiled with symbols at the time, I
> will re-run it and attach it here.
