Well I continue to read the documentation, however here are some observations:
1. Slapd is up and running all the time.
2. The service seems to go in a freeze mode for about 15 minutes or so and then responds again. 
3. Once it starts responding and I attempt to change password (using self service password)  it freezes again and does not respond for the next 15 minutes. 
4. This behavior happens even when not attempting to change the password but just some basic searches using phpldapadmin.
5. The server is adequately providing the needed memory and computing resources so dont this that is causing the issue.

Further any suggestions on what front end admin tool should be used with openldap.

Thanks and Regards,

Amit Dongaonkar

Sounds like either slapd is not running or you're attempting to connect in
an invalid fashion.  I'd suggest doing some reading on how to use the ldap
client tools, how to start slapd, how to use and connect to slapd, etc.
