Just like it is 2GB on 32-bit linux. Try building everything 64-bit. Another thing to try, from when I ran my servers on Solaris, is to fix the limits in /etc/system for the maximum amount of memory that can be allocated. I vaguely recall having to do this for my Solaris systems. Oh, and with BDB on Solaris, you want to use the "shm_key" flag in slapd.conf to use shared memory segments, when running on SPARC. Here's the last portions of /etc/system on my old Solaris LDAP servers: * turn off executable stacks set noexec_user_stack = 1 set noexec_user_stack_log = 1 * increase the size of the kernel stack to 24k for Solaris 8/64-bit set rpcmod:svc_default_stksize=0x6000 set lwp_default_stksize=0x6000 * force load the shared module kernel information. forceload: sys/shmsys * allow shared memory segments of up to 3 GB (default 1MB) * See http://www.sun.com/sun-on-net/itworld/UIR960101perf.html set shmsys:shminfo_shmmax=3221225472 * Increase memory performance when filesystem is being heavily used. * See http://www.sun.com/sun-on-net/performance/priority_paging.html set priority_paging=1 * Increase memory performance when filesystem is being heavily used. * See http://www.samag.com/documents/s=1323/sam0110e/0110e.htm set maxpgio=25468 set slowscan=500 * autoup influences how much RAM is checked by fsflush every 5 seconds. * Default = 30.

PS: 4GB of RAM is probably not enough for a 20GB database, you won't be able to configure caches large enough to get decent search performance. I think 8GB would be a practical minimum here.

No ideas, this problem doesn't occur on my Linux system. We've slapadd'd and slapcat'd databases of over a terabyte in size, with hundreds of millions of entries, and never seen slapcat grow beyond the size of the BDB cache. How large is your cache in DB_CONFIG?

(ITS#4703) mirrormode hole
by hyc＠OpenLDAP.org 06 Oct '06

06 Oct '06

Full_Name: Howard Chu Version: HEAD/re24 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (24.126.120.178) Submitted by: hyc If the current master commits an update but crashes before the change is propagated to the mirror, and then new updates are subsequently committed on the new master, the non-propagated changes will never be picked up, because the new master's context is newer than everything on the crashed master. The hole can be plugged by keeping a per-consumer contextCSN in addition to the overall contextCSN, so that the old state isn't lost. While we're at it, we should add a consumer option for specifying additional locations in which to store contextCSNs. This would e.g. solve ITS#4626 by allowing a consumer in a glued subordinate to keep its parent context up to date.

If the search returns exactly one entry, then there's no way it can be, say, returned twice, otherwise it would also when running aregular search. Moreover, I've recrated you scenario in 2.3.27 and HEAD, and everything seems to work as expected in all cases. I suspect something else is wrong, for example data in your DB is not like it appears. Usually, guessing and expecting is a bad practice when debugging software. Please perform offending operations with full logs on; check that your data is not duplicated (for example, you might not see duplicates because they're hidden by ACLs) and so. Unless you can show a clear malfunction of the software (which I don't see here) I'm inclined towards closing this ITS. p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

There is no slapmodrdn tool in OpenLDAP suite; I assume you mean ldapmodrdn. In any case, slapo-lastmod(5) is essentially unmaintained and basically useless.
