Exactly.  They are threads not processes.

No.  You LDAP service is using like ~4-6Mb of RAM. Total!  Thats
nothing.  I don't see any evidence of a memory problem.  Your using "0"
swap, so just don't worry about it.  "Free" RAM is wasted RAM,  you want
that number to be really low, or you can take that RAM out and stick it
into something that needs it.  Over time I'll wager the "Free" number
will fall as the system finds stuff worth buffering/caching.  This is
all CORRECT behaviour.
