In one server environment, I've found that slapd starts consuming CPU.  I ran it
-d-1 and it seemed to run ok.  Then I tried -d1.  That usually worked, but on
one occasion it ran away, too.  I think debugging affects the timing.  My belief
is that it's in a certificate retry loop of some sort.

I'll attach a log of the -d1 output showing some cert retries.  This run didn't
go into the loop, though.

The one debug -d1 which went into a compute loop was spewing these.  I managed
to ^C it, but also managed to delete the typescript, so I can't show the
thousands of retries on the one connection which had kept it busy.
