Hi! As I found out today, for some time our server has been producing numerous errors like these in the apache error log: [Fri Oct 02 00:51:43.567736 2015] [authz_core:error] [pid 9594] [client 127.0.0.1:60674] AH01630: client denied by server configuration: /var/www/abc.xy/ This line is produced for every domain (every symlink in /var/www/) once per minute. Both the pid and the port number change with every run. At first glance, this seems to be caused by the fact that in the virtual host files, the access to /var/www/abc.xy/ is blocked and access to /var/www/abc.xy/web/ is allowed - which totally makes sense. Do you have any idea which process might be scanning/trying to access these folders in that regular fashion? One suspect could be munin, but I don't really know how to confirm this and/or solve this problem, any help is appreciated! Kind regards and thanks in advance!
