Hello,

We have a clustered openldap server (slapd version 2.2.23 in two debian sarge servers). These servers are working perfectly as a user's repository from our others servers (mail servers, radius, etc.).

But now we are renovating our servers and we want to upgrade them to a new one based on openldap 2.3.30 (in two debian etch servers), but we are having problems.

In a test environment the new servers seems to work perfectly, but when we connect our mail servers to it we have a lot of errors. The mail servers seems to lost connection with the ldap. In the ldap serves the only errors we could find are a lot of:

Jul 5 09:44:33 canis4 slapd[28723]: conn=5087 fd=249 closed (connection lost)

It seems that it could be a network problem, but the network is the same than in the others.

We could thinking about a default parameter limiting connections or something like that...

Anybody has ever had this same problem? How could we solve it?

Thanks in advance
