Hi all,
damn i found the problem ... an earlier yum update has overwritten my self compiled slapd :(
Now everything is working as expected.

Hello list,
i hope you can help me with my problem.
To my setup:
All servers are OpenLDAP 2.4.42
I have an master LDAP server, which replicates with standard syncrepl to an
consumer ldap.
On this consumer ldap server i have configured an standalone slapd proxy
ldap with slapd-ldap which pushes changes to more than 6000 consumer ldaps.
There are more ldap proxys running, with each 500 consumers to reduce
startup time.
The master and slave are connected via TCP, and the ldap proxys are on the
slave via socket.
Everything works fine and changes are replicated in realtime to the
consumers behind the proxy, but after some time ( about 20 to 30 minutes ) the slave ldap just hangs and isnt responding anymore.
I'm not going to claim I had the same problem as you, but we had Java code that messed up a connection pool, and from the view of our OpenLDAP server, via strace we saw the process spinning on a wait on a file handle, and that file handle process to be one controlled by that Java code.
Until we cleaned up the Java code, our workaround was to introduce settings like this in our slapd.conf file:
idletimeout 30 writetimeout 60
