slapd crashing with password change

[luiz@pucrs.br]

Hello

I was installed openldap server in one Solaris 9 machine. Now, I´m
configuring it and there are a insolit situation.
I logged in one workstation without problemas. But when I tried to change
the password in one Linux client machine, slapd process die in the server,
without any log message (only one core dump file)! Then, I was started it
again with this option:

/usr/local/libexec/slapd -d 127 -h "ldap:/// ldaps:///"

The password was changed to anything unknown, in spite of the client
/etc/ldap.conf is setted to 'pam_password exop'. Then, I was tried to
change the password in the server, or delete the entire user. For my
terror, the slapd went wild. The message in the console, repetead for
eternity is:

bdb_cache_entry_db_lock: entry cn=user,ou=People,dc=my,dc=domain, rw 1, rc
-30995
====> bdb_cache_find_entry_id( 9 ): 9 (busy) 2
locker = -2147483582

I´m confused. Is anyone capable to help me?

My slapd.conf:

I was compiled the OpenLDAP with these options:

./configure --with-tls --with-ldbm --enable-wrappers --enable-crypt
--enable-bdb --with-cyrus-sasl --enable-slapd --enable-syslog
--enable-ipv6=no

Thanks a lot for any idea.
