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

No sooner had I configured <slapd.conf> as described below and then tested it

Any suggestions you can make as to different values for these parameters or 
other parameters, please let me know.  Also, I'd be willing to try a less 
memory-hungry backend if you think that'll help.
