I generally recommend to set idletimeout even somewhat tight in case you don't have a
strictly defined set of clients. Because a client application which does not use its LDAP
connection for ~5 min. is most times simply not closing connections. And running out of
file handles can affect all file creation on your system (e.g. creating BDB's transaction
log files).

Only the original poster can find out with monitoring.

One can find out stale connections via back-monitor in sub-tree
cn=Connections,cn=Monitor. IITC attribute 'monitorConnectionActivityTime' contains last
client access time on this connection.
(Ummh, I have to add this to my own monitoring script...)

And of course normal system monitoring of file handles would be also helpful.

Ciao, Michael.
