Thank you, I have installed the package:
gdb -q -x /root/gdb.init --args /usr/sbin/slapd -h ldap:/// ldapi:/// -g openldap -u openldap -f /etc/ldap/slapd.conf -l local5
Reading symbols from /usr/sbin/slapd...Reading symbols from /usr/lib/debug/usr/sbin/slapd...done. (no debugging symbols found)...done. [Thread debugging using libthread_db enabled] [New Thread 0xb5f06b70 (LWP 1387)] [Thread 0xb5f06b70 (LWP 1387) exited]
Program exited normally.

Problem: For a customer we use LDAP for many years. Last year suddenly the slapd service just stopped without any traces in the logfiles. After a restart of slapd everything works fine again. But the problem was there: it was not an incident, now and then slapd just stops and always without any traces in the logfiles. Sometime three times a day, sometime a week without a failure. I can't find a pattern or any relation to any other service on the linux server.
Attach to the running slapd with gdb, type handle all nostop continue and let it run. If there's a crash you'll see what happened in gdb.
I tried it but I don't get this working. I have no experience with gdb. I assume I do something wrong.
Normally slapd daemon runs like this on a test machine /usr/sbin/slapd -h ldap:/// ldapi:/// -g openldap -u openldap -f /etc/ldap/slapd.conf -l local5
If I try this running attached to gdb: su openldap -s /bin/bash gdb --args /usr/sbin/slapd -h ldap:/// ldapi:/// -g openldap -u openldap -f /etc/ldap/slapd.conf -l local5 GNU gdb (GDB) 7.0.1-debian .... This GDB was configured as "i486-linux-gnu". .. Reading symbols from /usr/sbin/slapd...(no debugging symbols found)...done.
May be it's agood idea to install the slapd package with debug infos.
aptitude search slapd i slapd - OpenLDAP server (slapd) p slapd-dbg - Debugging information for the OpenLDAP server
