Please turn on debug logging and watch the log files to see if you can see the connection from the clients and how the server responds. 

The issue may not be openldap per se but related to how your OS is responding to the TCP requests.  Make sure openldap is getting the requests.

man slapd.conf for debug options

I'm using OpenLDAP 2.3.30-5 on Debian 4 as a users database to replace flat files. I noticed that my clients sometimes fail to query the LDAP server and report 'Cannot bind .....(-1)', I think this error means they failed to reach the LDAP server, I checked the server and I can see it is running!
I had to restart the slapd again to make it work as before. This issue happens frequently and each time I have to restart slapd to make it respond to my clients, what is wrong? I'm using ldaps with a self-signed certificate.

Thank you
