RE: performance problem with sldap

hmmm.. i wonder if this is related to another thread in this mail list about memory leaks... do you check your slapd logs? i see that mine fails too if there are a lot of searches and I have to restart my slapd every now and then. how about we try an experiment run your 3000 searches and then restarted your server and run the other 2000 see if that works..
