Re: slapd-bdb cachesize

I use openldap 2.1.15/bdb-4.1.25 (dbd backend type) on Solaris 9 system

know if this is normal based on my configuration parameters. I am unclear
as to how does cachesize affect memory usage. Do you multiply this number
with the average entry size (and the number of threads?)? Is this param
neccessary to set in addition to DB_CONFIG tuning?
Good to hear someone has the same problem.
I also realized that my slapd is constantly growing, to IMHO rather
But: despite questioning this list unfortunately noone answered so far,
whether this is normal behaviour or not

In those mails you can find details about my setup.
My slapd's start with about 2.5 MB and grow by time slowly quite some MB
a day (in the first days faster of course, this seems to be the normal
caching). When it reaches about 300 MB I restart the process (which is
much more than one MB for each entry in the database!!!)
Meanwhile I tried inserting the checkpoint option in slapd.conf to avoid
also using lots of diskspace, this works fine so far, but doesn't seem
to reduce the memory hunger.
I also recompiled OpenLDAP with the new BDB related patch for Berkeley
DB (126.96.36.199) - but this doesn't seem to help, too.
Could you please give some more information about your setup, your
database, your indices, your usage - so we can compare and collect this
information? Maybe the others on the list can give us more hints then, -
the more they know the better they might help us, hopefully.
