We use 1.2.13 and get peaks of > 500 conns. Slaps fails at about 1000 
connections due to the use of select. I have a local workaround using
poll that is being 'tested' hard that will go as high as the limits
in the kernel. Even with only 20 or so conns we average 20-30 querys/s 
and see >100 queries/s at times. 

Just a thought.....

Have you checked with limit / ulimit before starting slapd that the soft
limit isn't set to something like 64. I have umlimit -n 1024 in my start
script to avoid cutting the server off earlier that it can handle.
