What he is almost certainly seeing is threads, not processes, and the
33Mb is cumulative not individual - they are all sharing the 33Mb.  This
is how Linux displays process information.

For that number of users I think 33Mb is SHOCKINGLY LOW.  You need to
tune the slapd cache size to let it use more memory.

Also 36 threads is insane,  your almost certainly swamping the
processor.  Limit your threads to something like 10 - 20 using the
threads directive in slapd.conf.

With the correct indexes and enough RAM it shouldn't really matter.
