slapd threads and processes...



Hi,

I have just migrated from iPlanet Directory Server to OpenLDAP 2 and 
everything seemed to be going very well.... however... I seem to be using loads of processes, and not dropping connections.

I am aware that there is a master slapd process that creates more threads as 
they are needed, but when I reached the maximum number of threads I allowed (100), slapd just grinds to a halt.

Could it be that I am not dropping connections? I have about 86 connections with TIME_WAIT when I do a netstat -a.

I have the info in my slapd.conf :

threads         100
idletimeout     300

Here is a section of what is output when I do a ps -auwxf | grep slapd

root     13044  0.0  1.9 72012 20244 ?       S    15:21   0:00 
/usr/lib/openldap/slapd
root     13045  0.0  1.9 72012 20244 ?       S    15:21   0:00  \_ 
/usr/lib/openldap/slapd
root     13046  0.1  1.9 72012 20244 ?       S    15:21   0:01      \_ 
/usr/lib/openldap/slapd
root     13051  4.5  1.9 72012 20244 ?       S    15:21   0:33      \_ 
/usr/lib/openldap/slapd
root     13052  1.9  1.9 72012 20244 ?       S    15:21   0:14      \_ 
/usr/lib/openldap/slapd
root     13096  2.1  1.9 72012 20244 ?       S    15:21   0:15      \_ 
/usr/lib/openldap/slapd

Most of my clients are Netscape address books, and searching for users seems 
to be much slower too.

Please can anyone suggest anything to help me!
