And in your reply, you copied the entire previous message - I've 
contacted Red Hat support to remove the messages from the archive.  But 
there is no way to revoke the messages once they are sent.

This information is interesting:

----- Total Connection Codes -----

B1                    11480    Bad Ber Tag Encountered
U1                     5877    Cleanly Closed Connections
T1                     2187    Idle Timeout Exceeded

B1 usually means the client just exit()'ed without first calling close() 
or shutdown() on the TCP/IP socket.  Which is fine.  It's the T1 which 
are odd.  Of these 2187, 1864 come from the same client:

13800  XXX.XXX.XXX.129
		   8254 -  B1   Bad Ber Tag Encountered
		   3608 -  U1   Cleanly Closed Connections
		   1864 -  T1   Idle Timeout Exceeded

Take a look at the access log where you get the T1 error upon 
disconnect.  You want to find out what the conn=XXXXX is.  From there, 
go back in the access log looking for the operations on that 
connection.  What are they?  What application are they from?  Why is 
that application opening connections and just leaving them open?  If it 
is a monitoring application like nagios, you will need to increase the 
idle timeout for that application.  You can do this by using a dedicated 
BIND dn for that application, then you can increase the idle timeout for 
that user without affecting any of the other users - see

If you have a lot of applications that open connections and leave them 
open for a long time, you will need to figure out how many file 
descriptors you need for other clients, and you will need to increase 
the number of file descriptors available for the directory server as 
well as the size of the directory server connection table -

information.
