I just noticed my PHP error log file is full of errors like this:
[Wed Sep 21 06:11:42.583837 2016] [:error] [pid 1533] [client 82.149.23.23:50727] PHP Fatal error: require():Failed opening required '/www/delivery/../../lib/OA/Dal/Delivery/.php' (include_path='.:/usr/share/php:/usr/share/pear') in /www/delivery/lg.php on line 1977, referer: xxx
This happens every minute or so, although the ads are being served more often and I haven't noticed any issues with ads delivery.
I have no idea where to start debugging or how to figure out in which case this happens. I did check that line and looks like it fails to get database type from $GLOBALS['_MAX']['CONF'].
Any ideas?
Thanks!
