Maybe you have set a high loglevel in slapd.conf, or you are using the
slapd '-d' argument.

Loglevel is what gets logged to syslog.  Default logevel is 'stats'
(256), which gives a few lines per LDAP request.  Some years ago our
site had to set loglevel=0 because it could not handle all the
syslogging, but a hardware upgrade fixed that.  Default syslog
user.level=local4.debug, see man slapd.

Yes, monitor is memory-only.
