Yeah the DAVLock issue is not there now.
I guess it should not come up again after the server restart.
As after that the httpd.conf file is regenerated. But it will not come as now I enabled the mod_DAV stuff on my subversion page at server-manager as told by you in the earlier post.
Hoping for good,
Though I am not restarting my server for now ...
Thanks and Regards
