Too many open files: /.htaccess pcfg_openfile

Question

Apache HTTP Server

Recently, the server began to fall off periodically. Tech support wrote that an error constantly occurs in the logs:

Too many open files: /.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable

Googling doesn't provide much useful information. Has anyone experienced something similar? And how did you decide?

Answer 1

Add ulimit -n 16384 to /etc/init.d/httpd (apache init script) and then restart apache. Perhaps it will help.

Answer 2

OpenVZ for sure?
cat /proc/user_beancounters
show.
Most likely, you are running out of numfile.

Answer 3

chcon -R -t httpd_sys_content_t /home/www on centos 7 helped, sorry for the necroposting
