Ping? Without said info, this ITS will be closed.

Sounds like you need to configure an idletimeout in slapd. Software usage
questions belong on the openldap-software mailing list. This ITS will be closed.

The point in defining these macros based on BDB_IDL_LOGN is that you can
simply change that single value, rather then editing everything else that
depends on it.
E.g., change BDB_IDL_LOGN to 17 and leave the other two definitions untouched.

It all depends on the sequence in which entries are added to the database. If
the majority of entries belonging to a particular index slot are created at
around the same time, then they will fit easily into the index and there will
be no problem. If there is a large gap in entries/time, and the gap exceeds
the BDB_IDL_DB_SIZE, then the problem will occur again.
> What is the limit and drawback?
The limit is simply the amount of RAM you have available on your machine.

Thank you, Howard,
I have installed in the morning slapd from CVS, enabled the caches on
the servers and they have running the whole day without any cache
corruption.
Now, from time to time, there appears segmentation fault. I will post
another ticket because it seems unrelated to the issue discussed here.

(ITS#6308) replication locks with delta-syncrepl
by quanah＠zimbra.com
Full_Name: Quanah Gibson-Mount
Version: 2.4.18

URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (75.111.29.239)
OpenLDAP 2.4.18 with BDB 4.7.25, fully patched.
Delta-sync replication works fine as long as the system is not loaded. Once it
is loaded, replication will fail after a while, waiting on a transaction.

(ITS#6200) slapd crashes under load w/ syncrepl
by frank.offermanns＠caseris.de
Hello,
i have the same problem with 2 Ubuntu 9.04 Systems with the current build
from HEAD. I created 20000 entries at server1. Then i created another
20000 entries at server1 while reading the old and new entries from
server1 and server2.
Here is the backtrace:
slapd: pthread_mutex_lock.c:289: __pthread_mutex_lock: Assertion `(-(e))
!= 3 || !robust' failed.
Program received signal SIGABRT, Aborted.

This is now fixed in HEAD overlays/pcache.c. The bug occurred because the
cache was seeing a child entry first, and so the dc=justillusion.net object
got created as a glue entry. Later when the actual dc=justillusion.net entry
was received, the modify to store its true values in the cache DB failed
because it needed the manageDSAit control.

Hello,
I have recompiled slapd (2.4.18-release) on another machine (i386) in
order to see if the bug is architecture dependent - the other servers
are on amd64 architecture. It shows the same bug.
The log file could be found here:
http://purgatory.spnet.net/~karavelov/d2
for the failing record, search for:
filter="(&(objectClass=mailDomain)(dc=justillusion.net))"
It does not fail with "scope not ok" error, but with "bdb_search: no
candidates". I have seen the same error appear on the other servers
(amd64) but I had trouble to isolate the whole history of the query. On
this test server I have seen the other error too ("scope not ok") so the
failing mode is not architecture dependent.
I have also noticed that there are some messages like:
bdb_add: dn2id_add failed: DB_LOCK_DEADLOCK: Locker killed to resolve a
deadlock (-30995)
May be this is in the source of the errors I see ?
The used config could be found here:
http://purgatory.spnet.net/~karavelov/slapd.conf.h2
Thanks in advance for help and suggestions
