RE: Ldap or bdb hangs....
HI all,
Well there are some good news, but...
With this configuration:
SLAPD.CONF
loglevel 2048
conn_max_pending 1000
idletimeout 15
sizelimit 25000
threads 64
timelimit 30
database bdb
suffix "dc=pt"
directory /db
index default pres,eq
index objectclass
index uid
index uidNumber
access to * by * read
And DB_CONFIG:
set_lg_bsize 2097152
set_lg_max 10485760
set_lg_dir /var/log/bdb
set_cachesize 0 536870912 1
set_lk_max_locks 50000
set_lk_max_lockers 1000
set_lk_max_objects 4000
set_flags DB_TXN_NOSYNC
set_lk_detect DB_LOCK_YOUNGEST
Th slapadd command runs very fast... Before it took about 5minutes to insert
15000 entries... And now it take only a few seconds..... But the problems
with the searchs performance remains!!!!!!! :|
The client still take long time to response when there were more than 20/30
connections... And strangely it starts appearing at the logs:
Nov 5 15:49:27 ldap slapd[2777]: <= bdb_equality_candidates: (objectClass)
index_param failed (18)
Nov 5 15:49:27 ldap slapd[2777]: <= bdb_equality_candidates: (uid)
index_param failed (18)
BTW: Fredriksson, in my logs doesn't appear any BDB logs indicating problems
in cache or some invalid arguments

Have you already solve it or discover where it came from?
Because Quanah Gibson-Mount is saying that this problems maybe come from
other areas and not only, I think, with the configuration settings, like
threading...

So you're saying that your's "start working again" after "a while"? How long
roughly? Just wondering if you're having the same problem as I, or if it's
completley different...
