I'm running fedora directory server on some boxes in a multi-master arrangement.
The problem is that when dirsrv is lauched from init (on boot) the maximum number of allowed file descriptors (ulimit -n) is only 4096. That means that the slapd process can only accept ~4k connections, and it needs to accept ~10k or so.
The value for nofile for all users in /etc/security/limits.conf (and limits.d/*) is 65536, and as soon as I restart the process (service dirsrv restart) it comes up with ulimit -n being 64K, the way it's supposed to. Why isn't it doing this at boot?
Right after boot: ldap07:~ mpatenaude$ ldapsearch -x -h localhost -LLL -D 'cn=directory manager' -W -b 'cn=config' -s base nsslapd-maxdescriptors Enter LDAP Password: dn: cn=config nsslapd-maxdescriptors: 4096
ldap07:~ mpatenaude$ sudo service dirsrv restart [sudo] password for mpatenaude: Shutting down dirsrv: ldap07... [ OK ] Starting dirsrv: ldap07... [ OK ]
ldap07:~ mpatenaude$ ldapsearch -x -h localhost -LLL -D 'cn=directory manager' -W -b 'cn=config' -s base nsslapd-maxdescriptors Enter LDAP Password: dn: cn=config nsslapd-maxdescriptors: 65535
