Re: Log files building up with large group

I have directory with a group with ~220,000 users in it.  This group is
frequently updated (several times an hour).  This appears to be causing
the BDB transaction logs to grow very large; over the course of a day
they grow to about 36GB.  These all appear to be active; neither
'slapd_db_archive -d' or DB_LOG_AUTOREMOVE has any effect.

Is there anything that can be done about this or is this an unavoidable
side-effect of the transaction system?

What version of BDB are you using? Have you configured a checkpoint in slapd.conf? What version of OpenLDAP are you using?

There were some bugs in some versions of BDB and I think some version of OpenLDAP that failed to properly checkpoint, causing the issue you are seeing. A properly patched version of BDB and a current release of OpenLDAP should certainly not have this problem.
