Rudder

Ah, these are BerkeleyDB log files. They are useful for replaying transactions to recover a corrupt database (this can happen if your disk gets full, slapd is killed or your server crashes).

However, you have a good point that keeping them forver is not useful. I will adapt this bug to implement an option to auto-clean them.

In the mean time, you can clean them up yourself with the following procedure, run as root (Debian/Ubuntu specific):

# Find package name for db-utils (Debian/Ubuntu specific)
DB_VERSION=$(ldd /opt/rudder/sbin/slapcat | grep libdb | sed 's/^[ \t]*libdb-\([0-9\.]\+\)\.so => .*$/\1/')
DB_UTIL_PKG="db${DB_VERSION}-util" 

# Install the db-util package adapted to the version of BerkeleyDB actually in use
apt-get install ${DB_UTIL_PKG}

# Run db_archive to remove useless files
/etc/init.d/slapd stop
cd /var/rudder/ldap/openldap-data
db${DB_VERSION}_archive -d
/etc/init.d/slapd start

Applied in changeset cb6b7aa3ac8142a136c2b9b9b61a979fc42226bd.

It seems OK to me.
