Dear All,

I have an openldap server which is not able to cater to all the
connection requests it is getting. It stops responding - ie. clients
which attempt a connection get an error 'Can't contact LDAP server (-1)'
after about 2 - 3 minutes of trying. There is high traffic and the
problem occurs throughout the day - the server responds, then reaches a
peak - stops and then responds again. 
Kindly guide me - all help is greatly appreciated. Thanks in advance.

Kindly provide relevant and useful information, such as:

OpenLDAP Release
BDB version and patch level
Size of database on disk
DB_CONFIG parameters
slapd.conf/cn=config tuning done (cachesize, idlcache, etc)
OpenLDAP backend being used (back-hdb, back-bdb, back-sql, etc)
Total system memory
32 or 64-bit system
