Version: 2.0.27
OS: linux 2.4.22

SYSTEM DESIGN:
6 servers running OpenLDAP (1 master and 5 slaves) holding about 100000 unix
accounts,
300 various web accounts and about 4000 domains. Master and one of the slaves
are
running OpenLDAP 2.0.25, while others are running 2.0.27. This Directory is used
for
system-wide authentication and for storing sendmail maps and classes  for our
smtp relay
cluster (we also plan to store dns tables there).

In the beginning, this directory was used only for various types of user
authentication.
When a user tried to login to our access servers and his/her modem didn't
negotiate
error correction, AS would send trash as a username to radius, which in turn,
would
pass it literaly to nss_ldap which would form a search string that could crash
slapd.
I 'fixed' the problem by adding username sanity check to nss_ldap and didn't
investigate
the problem further. Since then, slapd ran stable and we didn't have any
problems,
but the problem is obviously still there. I've mentioned this because the
problem we are
experiencing now is possibly connected to this problem.

SERVER PLATFORM:
- Master and one of the slaves are both running OpenLDAP 2.0.25 on SuSE 7.2
Linux,
  SMP kernel 2.4.18-grsec-1.9.4 on Dual PIII @ 1 GHz, 2 Gb RAM, Intel STL-2
motherboard,
  RAID5 array. GLIBC version is 2.2.2, DB version 3.1.7 (used for ldbm
backend).
- Remaining 4 slaves are running OpenLDAP 2.0.27 on Slackware 9.0 Linux,
  SMP kernel 2.4.22 on Dual Xeon @ 2.8 GHz, 2 Gb RAM, Intel SE7501CW2
motherboard,
  RAID5 array. GLIBC version is 2.3.1, GDBM version is 1.8.0 (used for ldbm
backend).

SLAPD CONFIGURATION:
These are the most important parts of slapd.conf...

include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/cosine.schema

PROBLEM DESCRIPTION:
Ever since we configured sendmail (8.12.10) on our smtp nodes to fetch its maps
and
classes from our OpenLDAP directory, slapd began to crash at, apparently, random
intervals.
At first, I thought this was caused by trash e-mail addresses, similarly to the
previous radius
problem, but I couldn't find anything in the sendmail logs that would confirm my
asumption,
nor I could reproduce the problem manually. Running slapd with various debug
levels didn't
give me any clues either, as it still appeared random. So, at the end, I
recompiled slapd
with debugging and saved a few core dumps to investigate. The exact same
symptoms I
had with OpenLDAP 2.1.23 and 2.0.25 when I first tested the system with those on
both
hw/sw platforms, although I didn't try to debug them. These backtraces are from
OpenLDAP
2.0.27 coredumps. Of course, I will provide any additional info if necessary.
