[Pkg-openldap-devel] Bug#519511: slapd uses too much memory

[Antonis Christofides]

Package: slapd
Version: 2.4.11-1
Severity: important

When slapd starts on my system it consumes something like 7M of RAM
(about 50M virtual). As time passes, it consumes more and more,
reaching hundreds; after 24 hours it uses something like 400M or 500M.
This is a very small LDAP database; the LDIF file is 315K.  Therefore,
I don't see any reason for such usage. The backend is BDB, and the
DB_CONFIG file says:

set_cachesize 0 2097152 0
set_lk_max_objects 1500
set_lk_max_locks 1500
set_lk_max_lockers 1500

This happened after the upgrade to lenny (at the same time I upgraded
the machine's RAM from 1 GB to 4 GB, but I don't think that this
should make any difference).

If you need more information, I can debug it if you give me some
debugging hints.
