Hello
I am having problems with openldap when the size of the entries reaches 3
000 000 entries.
I am using openldap-2.3.14 and db-4.4.16
The hardware has 4 G of memory running Centos 2.6.9-22 on a 32 bits plateform
I can slapadd the 3 000 000 entries without problem
The content of the bdb reaches a total of 3.7G
-rw------- 1 root root 806M Jan 5 12:33 dn2id.bdb
-rw------- 1 root root 2.9G Jan 5 12:33 id2entry.bdb
When i try to search the entries, i can see the slapd process reaching 3.2 G
in memory and suddently stopped
slapd-2.3.14: ch_malloc.c:107: ch_calloc: Assertion `0' failed.
Aborted
My slapd.conf:
##############
database bdb
suffix ""
rootdn "cn=Admin"
rootpw admin
directory //usr/ldap//openldap/var/openldap-data
# Indices to maintain
loglevel 0
cachesize 500000
#tried cachesize 3500000
#tried cachesize 1000000
#tried cachesize 100000
index uniqueID eq
My DB_CONFIG
############
set_cachesize 1 0 2
#tried set_cachesize 0 20000000 2
#tried set_cachesize 0 512000000 2
I have tried a lot of different (cachesize/set_cachesize) parameter in
slapd.conf / DB_CONFIG configuration but i get the same result.
I know that i am reaching the memory size limit of a linux process.
Any idea what is going wrong & what needs to be done ?
Thanks in advance
