Hi, list.
I'm using openldap-server-2.3.35 on FreeBSD 6.2-STABLE (Feb 19).
I have reproduceble crash of slapd on this host. But I can't reproduce
it on other server (FreeBSD 6.1-STABLE Aug 2).
Database is fine (I dump and restore it), changing thread library
doesn't help too.
Some information from core:

May be related to ITS#4841. Perhaps the thread stack is being overrun,
you might try recompiling libldap_r with a larger thread stack size.

Hi Howard,
Dmitriy followed your recommendations and rebuilt the openldap-server-2.3.35
port with the following variables set:
LDAP_PVT_THREAD_STACK_SIZE=268435456
WITH_DEBUG=yes
STRIP=""
He sent me more gdb output (bellow). Also, I have a test case which I use to
reproduce the crash (attached). Hope this will shed more light on the problem.

We find problem -- unique overlay.
When we remove this strings:
overlay unique
unique_base ou=users,o=oilspace
unique_attributes mail
problem is gone.
I tried add "unique_strict" but it doesn't help.

Did you make sure the overlay directives came at the very end of the
database configuration section? I've used unique for a long time with no
issues.

I'm sorry for long pause.

I'm positive the issue is caused by the "index" directives coming
__after__ overlay instantiation, while they belong to the database
configuration. This issue has been fixed in HEAD/2.4 by partially
redesigning the way configuration is parsed, but it is not possible (I
mean: not worth the effort) to fix in 2.3, since it essentially appears
as a configuration error (configuration order matters).
