> 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:
> 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):
> 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.
