Have you tried adding a ulimit command to raise the number of open files in the apache start script or systemd service file?

I have done two tests - one from shell and one through the apache web server. Both tests open as many files as possible in a given folder (named a-00001.dat, a-00002.dat and so on). The initial test resulted in 1006 open files through the apache web server, and about 1020 from the shell. By playing with the /etc/security/limits.conf and /etc/sysctl.conf I managed to increase the number of files from the shell to about 2000 (then the limit was set to 8190 files (soft limit was 8192 in /etc/security/limits.conf). But through the apache web server, it is still only 1006. The content of /etc/security/limits.conf: * soft nofile 8192 * hard nofile 16348 apache soft nofile 8192 apache hard nofile 16348 The apache web server was restarted after I changed the /etc/security/limits.conf file. I executed 'print_r(posix_getrlimit())' in a php script through the apache web server and got this output: Array ( [soft core] => unlimited [hard core] => unlimited [soft data] => unlimited [hard data] => unlimited [soft stack] => 8388608 [hard stack] => unlimited [soft totalmem] => unlimited [hard totalmem] => unlimited [soft rss] => unlimited [hard rss] => unlimited [soft maxproc] => 62856 [hard maxproc] => 62856 [soft memlock] => 65536 [hard memlock] => 65536 [soft cpu] => unlimited [hard cpu] => unlimited [soft filesize] => unlimited [hard filesize] => unlimited [soft openfiles] => 1024 [hard openfiles] => 4096 ) For me it seems like php is setting a limit, or??
