OpenLDAP fails on reboot

[Digant Kasundra <digant@uta.edu>]

Hello everyone,

I'm running OpenLDAP 2.2.8 and bdb 4.2.52 on redhat enterprise linux as 3.0.
When I first configured everything (namely the slapd.conf and the DB_CONFIG
files), and fired up OpenLDAP, it worked great.  I could bring it up and
down and up and down and up and down and it worked just fine.  But on
reboot, it never comes up and I have to run db_recover first.  Afterwards,
it runs just fine, until the next reboot.


slapd startup: initiated.
bdb_db_open: dbenv_open(/usr/local/var/openldap-data)
bdb(dc=uta,dc=edu): shmat: id 0: unable to attach to shared system memory
region: Invalid argument
bdb_db_open: dbenv_open failed: Invalid argument (22)
backend_startup: bi_db_open(0) failed! (22)
slapd shutdown: initiated
====> bdb_cache_release_all
slapd shutdown: freeing system resources.
bdb(dc=uta,dc=edu): txn_checkpoint interface requires an environment
configured for the transaction subsystem
bdb_db_destroy: txn_checkpoint failed: Invalid argument (22)
slapd stopped.
connections_destroy: nothing to destroy.


Here is the juicy stuff from my slapd.conf:

threads 20
lastmod on
database bdb
shm_key 5
checkpoint 1025 5
cachesize 50

(Note: I get the same problem with shm_key 8 and 4, etc, and checkpoint
should probably be 1024 but that didn't help matters eithers).

Here is the DB_CONFIG:
set_cachesize 0 25165824 1
set_lg_regionmax 262144
set_lg_bsize 262144


Anyone have any ideas?
