I have an Ubuntu 14.04 LTS server, multiple websites running on it. http://martion.alomvilag.hu is one of them.
Site is usually working, but from time-to-time it provides a 403 response and Forbidden message:
I checked error logs, and the only error I found is this:
(24)Too many open files: [client 184.108.40.206:44991] AH00529: /var/www/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that '/var/www/' is executable
I checked resources on that and
no selinux on our system
/var/www/martion.alomvilag.huare all 755,
My main concern is that this is only happening sometimes, without pattern and after a refresh or two it is working again. Anyway it is really unpleasant to any of our users. Do you have any advice?
