What's your operating system again?  Opening a ticket on this sounds
appropriate to me.  Do you have a debugger available?  Last I recall
you were talking about using truss to view the system calls.  With
a debugger you can attach to the process running in the background,
set a breakpoint on the time() call and then back yourself up the
stack until you get to some OpenLDAP slapd code.  You ought to be
able to do a "where" from there.

With gdb, it would be "gdb /usr/local/libexec/slapd pid"
where pid is the process id # of slapd.
