I'm testing mdb since the last versions with our dataset. If I use my production config slapd does't start up.

The following is in the log file.

Sep 11 16:48:37 ds71 slapd2.4[8349]: @(#) $OpenLDAP: slapd 2.4.32 (Sep 6 2012 13:50:54) $#012#011mschirrmeister@defrsl6bh2.ogilvy.com:/home/mschirrmeister/rpmbuild/BUILD/openldap-2.4.32/servers/slapd Sep 11 16:48:37 ds71 slapd2.4[8349]: mdb_attr_dbs: database "dc=ogilvy,dc=com": mdb_open(omgPublishDate) failed: Too many open files in system (23). Sep 11 16:48:37 ds71 slapd2.4[8349]: backend_startup_one (type=mdb, suffix="dc=ogilvy,dc=com"): bi_db_open failed! (23) Sep 11 16:48:37 ds71 slapd2.4[8349]: slapd stopped.

My /etc/security/limits.conf file has already the following entries. * soft nofile 65535 * hard nofile 65535

No matter what I try on the OS side, the error above comes up.

I have about 130 index attributes in my config. Looks to me that this is the problem. If I comment 8 attributes, slapd starts fine.

I did not find anything about index limits. Is this a bug in mdb? I'm not able to create stacktrace. When I run slapd via gdb, output is this.

Program exited with code 01. (gdb) bt full No stack. (gdb)

If you can let me know how to do it, I can provide a trace.

My config looks like below. I omitted all our internal attributes.
