I made some tests, and it seems that it happens with client activity.
If I run the same ldapsearch command in a loop, slapd memory usage
(as reported by ps) goes up by about 1 byte per command. For example,
I run it 1000 times, resident goes up by about 1000 bytes (sometimes 980
or so); virtual also goes up, sometimes 1400, sometimes 500, sometimes
something in between. (If I don't do such a test, slapd memory usage
can stay the same for a minute or so, probably because client activity
is normally very little.)

I attach my slapd.conf.

I will also take a look into valgrind, never used it.
