We're trying to run OpenLDAP 2.0.21 in a production environment supporting unix logins and samba. We have a serious problem thats started to happen more and more in the last few weeks (probably load related). About 3 times a day, the LDAP server just stops responding. The log files of clients complain they can't contact the LDAP server. The server is still running, it's just that no one can connect. Many commands on the clients just return "broken pipe." This is a serious problem and it's causing a lot of problems, especially with our mail server. Users are getting bumped from mailing lists because these periodic outages cause sendmail to report "Unknown users." Has anyone experienced this? Is it just that OpenLDAP doesn't scale? We only support about 4000 users on one server. I'd turn on debugging but I don't know what level would be appropriate. Too much debugging output slows OpenLDAP way down and the users notice very slow logins. Thank you. If I could just solve this huge problem, I'd be very happy with OpenLDAP. thanks, Michael -- Public key available from http://students.cs.byu.edu/~torriem
