Openldap/bdb instability

[Olle.Westman@astrazeneca.com]

Hi, I've configured openldap-2.1.12 with sleepycat's bdb (db-4.1.25).
The ldap server runs awhile but then gets filled with error messages:

Feb 6 11:11:13 7U:server01 last message repeated 140 times
Feb 6 11:11:15 7U:server01 slapd[170848]: <= bdb_equality_candidates:
index_param failed (18)

after a while the error messages are very many, and it all ends with a
failure to allocate bytes with ch_malloc,
and slapd dumps core.

Anyone recognizes these errors? slapd stands up for about 15-20 minutes with
about 100 clients accessing it as a source
for name lookups.

Regards,
