use libtcmalloc_minimal.so.4.1.2
add export LD_PRELOAD=3D/opt/local/tcmalloc/lib/libtcmalloc_minimal.so to my
run script
run slapd and view pmap pid to make sure that tcmalloc are using
run load script - 3K mps on two servers (1.5K mps per server)
load for 30 minutes memory consumption increased from 366 Mb to 660 Mb and
rising.

libtcmalloc did not help me
