Re: (ITS#3609) ch_malloc of 8388608 bytes failed

I changed the value of <searchstack> from 4 to 8 and re-ran the program with the 
same results also uploaded to my website (this time I included <slapd.conf>):

There is only one <slapd.conf> file around, so there should be no confusion.

Many, many thanks for your time and effort.
